Answer:
C. DHCP is a distributed protocol and the broadcast packets ensure that servers are synchronized.
Explanation:
DHCP (dynamic host configuration protocol) is a server based protocol that provides clients or nodes in a network with dynamically configured services such as assigning ip addresses, DNS, default gateway etc.
It is a broadcast protocol, given that for a client to seek services from a server, it sends a broadcast traffic to the server or servers in the network. The dhcp protocol forwards this message to all the servers to synchronize them, so only one server responses to the request and the servers updated.
Importance of the need for workstation policies and LAN Domain policies.
Workstation and LAN Domain policies are crucial for defining rules around account security, including password creation, account reactivation, and secure internal communication. These policies protect digital systems from unauthorized access and misuse while preparing the organization for future technological advancements. They create an ethical framework for users to interact with the organization's technological resources.
The importance of having workstation policies and LAN Domain policies lies in maintaining a secure and efficient technological environment within an organization. Account policies can be defined for a domain to enforce rules on user accounts, which include Password Policies, Account lockout policies, and Kerberos Policies. These policies help in regulating access, enhancing security, and setting user expectations through acceptable use policies (AUPs).
For instance, password policies ensure users create strong passwords, which need to be changed after a certain period, increasing the security of organizational systems. Account lockout policies, on the other hand, define the process of regaining access to an account, minimizing the risk of unauthorized access. The Kerberos policy, which is part of a domain's security policy, facilitates secure communication within networks.
Additionally, the use of technology policies needs to accommodate for future innovation and the impact of technology on the workplace and families. Organizations, including school districts, should have clear Technology Use Policies that outline the appropriate use of their systems and the potential consequences of misuse to ensure that all users are aware of the ethical use of computational system.
An over-target baseline (OTB) is a comprehensive rebaselining effort that is best categorized as an internal replanning effort.
A. True
B. False
Answer:
The answer is "option B".
Explanation:
An OTB stands for an over-target baseline, it is a new management benchmark when an original target can't have coincided and new goals for management purposes are required.
It is also known as a reference to the foundation for calculating or constructing. It is an understanding between the client and the contractor that the cost base, which is not part of the original contract budget, should include an extra budgetWhich of the following class definitions is correct in Java?(i)public class Student{private String name;private double gpa;private int id;public void Student(){name = "";gpa = 0;id = 0;}public void Student(String s, double g, int i){set(s, g, i);}public void set(String s, double g, int i){name = s;gpa = g;id = i;}public void print(){System.out.println(name + " " + id + " " + gpa);}}(ii)public class Student{private String name;private double gpa;private int id;public Student(){name = "";gpa = 0;id = 0;}public Student(String s, double g, int i){set(s, g, i);}public void set(String s, double g, int i){name = s;gpa = g;id = i;}public void print(){System.out.println(name + " " + id + " " + gpa);}}1. Both (i) and (ii)2. None of these3. Only (ii)4. Only (i)
Answer:
The answer is "Option 3".
Explanation:
In the given question the code (ii) is correct because in the class definition class "Student" defines a constructor that does not use any return type. and code (i) class definition the class "Student" defines a constructor that uses return type void which is not allowed in the constructor. and other options are not correct that can be described as follows:
In option 1, only code (ii) is correct.In option 2, code (ii) is correct that's why it is not correct. In option 4, it is not correct, because it uses void return type.
1. True/False:
Mark either T (true) or F (false) for each statement in below. Write in one short sentence why you chose that answer, if necessary. You may lose points if your answer is very long.
a. Adjacency lists are more space efficient than adjacency matrices for sparse graphs. A sparse graph G = (V,E) has |E| = O(|V|).
b. The maximum number of edges in a graph with n vertices is n (n +1) / 2 .
c. A spanning tree of a graph with n vertices contains n edges.
d. Dijkstra’s algorithm does not work on directed graphs.
e. A dynamic programming algorithm makes short-sighted choices that are locally optimal.
f. Dynamic programming is an appropriate choice to solve merge sort.
g. Prim’s and Kruskal’s algorithms are examples of greedy algorithms.
h. In a flow network, the capacity of an edge must be less than or equal to the flow on the edge.
i. Dynamic programming uses memoization to avoid solving the same subproblem more than once.
j. Choice of data structures do not impact the time complexity of graph algorithms.
Answer:
(a) - True
(b)- False
(c)- False
(d) - False
(e) - False
(f) - False
(g)- True
(h)- False
(i) - False
(j) - False
Explanation:
(a)- In an adjacency list the usage of space depends upon the number of edges and vertices in the graph while in the case of the matrix efficiency depends upon the square of the vertices.
(b) The maximum number of edges is n*(n-1).
(c) The number of edges with a spanning tree of n vertices contains n-1 edges.
(d) Dijkstra's Theorem simply refers the adjacent vertices of a vertex and is independent of the fact that a graph is directed or in directed.
(e) Greedy Algorithm makes short sighted choices
(f) Consider the term overlapping sub-problems which is the technique used in Dynamic programming it uses previous calculations to find optimal solutions however in case of merge sort the idea is to break down array into smaller pieces that don't overlap unlike dynamic programming.
(g) Prim and Kruskal's algorithm are examples of greedy algorithm because the use the idea to pick the minimum weight edges at every step which is the approach of a greedy algorithm.
(h) the amount of flow on an edge cannot exceed its capacity.
(i) Dynamic Programming can be implemented using tabulation too.
(j) Different data structures have different time complexity.
Suppose there is a class Roster. Roster has one variable, roster, which is a List of tuples containing the names of students and their number grades--for example, [('Richard', 90), ('Bella', 67), ('Christine', 85), ('Francine', 97)]. Roster has a function findValedictorian that returns the name of the student with the highest grade. Find the valedictorian of the Roster object englishClass and store it in the variable valedictorian.
Answer:
class Roster:
def __init__(self,student):
self.student = student
def findValedictoian(self):
highscore = 0
studentList=[]
bStudent = []
valedictorian =''
for pupil in self.student:
if pupil[1] > highscore:
highscore = pupil[1]
valedictorian = pupil[0]
return valedictorian
student = [('rich', 90), ('Bella', 67),('philip', 56)]
englishClass= Roster(student)
print(englishClass.findValedictoian())
Explanation:
we define the roster class using the class keyword, within the class we have our __init__ constructor and we initialize the variable student.
A class method findValedictoian is defined and it compares the grades of each student and returns the name of the student with the highest grade.
An instance is created for English class and the findValedictorian method is called and the valedictorian is printed to the screen.
Given an input array of strings (characters) s, pick out the second column of data and convert it into a column vector of data. Missing data will be indicated by the number 9999. If you encounter missing data, you should set it to the average of the immediately neighboring values. (This is a bit simpler than using `interp1`.)
If the input array is s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ]; then the output variable `t` is the following column vector. t = [96 114 109.5 105 112]';
Compose a function read_and_interp which accepts an array in the above format and returns the data converted as specified. You may find the conversion function `str2num` to be useful.
(Using MATLAB Syntax only)
Answer:
Consider the following code.
Explanation:
save the following code in read_and_interp.m
function X = read_and_interp(s)
[m, n] = size(s);
X = zeros(m, 1);
for i = 1:m
if(str2num(s(i, 2:5)) == 9999)
% compute value based on previous and next entries in s array
% s(i, 2:5) retrieves columns 2-5 in ith row
X(i,1) = (str2num(s(i-1 ,2:5)) + str2num(s(i+1,2:5)))/2;
else
X(i,1) = str2num(s(i,2:5));
end
end
end
======================
Now you can use teh function as shown below
s = [ 'A' '0096' ; 'B' '0114' ; 'C' '9999' ; 'D' '0105' ; 'E' '0112' ];
read_and_interp(s)
output
ans =
96.000
114.000
109.500
105.000
112.000
Define a function below called nested_list_string. The function should take a single argument, a list of lists of numbers. Complete the function so that it returns a string representation of the 2D grid of numbers. The representation should put each nested list on its own row. For example, given the input [[1,2,3], [4,5,6]] your function should produce the following string: "1 2 3 \n4 5 6 \n" Hint: You will likely need two for loops.
Answer:
The solution code is written in Python:
def nested_list_string(list2D): output = "" for i in range(0, len(list2D)): for j in range(0, len(list2D[i])): output += str(list2D[i][j]) + " " return outputExplanation:
Let's create a function and name it as nested_list_string() with one input parameter, list2D (Line 1).
Since our expected final output is a string of number and therefore we define a variable, output, to hold the string (Line 2).
Next use two for loops to traverse every number in the list and convert each of the number to string using str() method. Join each of individual string number to the output (Line 3-5).
At the end, we return the output (Line 7)
The 'nested_list_string' function converts a list of lists of numbers into a string that visually represents a 2D grid, with each sublist converted to a row of numbers separated by spaces, and rows separated by newlines.
The function called nested_list_string should be defined to take a list of lists of numbers as its argument and return a string representation of the 2D grid. To achieve this, you will need to use a nested for loop. The outer loop will iterate over each sublist (which represents a row of the grid), and the inner loop will iterate over each number in the sublist, converting it to a string and appending it to a string variable along with spaces. The \n character is used to move to the next line after each sublist is processed, thus simulating rows.
Here's an example code:
def nested_list_string(list_of_lists):Given an input like [[1,2,3], [4,5,6]], the nested_list_string function would return '1 2 3 \n4 5 6 \n'.
To print the last element in the array named ar, you can write :A. System.out.println(ar.length);
B. System.out.println(ar[length]);
C. System.out.println(ar[ar.length]);
D. None of these
Answer:
Option (d) is the correct answer.
Explanation:
An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.
In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--
System.out.println(ar[ar.length-1]);
No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--
Option a will prints the size of the array.Option b also gives the error because length is an undeclared variable. Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.In a class, why do you include the function that overloads the stream insertion operator, <<, as a friend function? (5, 6)
Answer:
To provide << operator access to non-public members of the class.
Explanation:
Whenever we overload << operator, an object to ostream class has to be passed as this is the class which has properties which allows printing of output to console. Moreover, this operator is used outside class all the time so if not made a global member it will produce conflicts so thats why it has to be made a friend function to allow efficient access to private members of the class. Its declaration inside class is as follows :
friend ostream& operator<<(std::ostream& os, const T& obj) ;
Modern operating systems support multitasking by doing what?A) Keeping pending jobs available in memory as processesB) Sharing input and output devices between usersC) Distributing tasks as threadsD) Using hard disk space as an extension of memory
Answer:
Option A is the correct answer to the following question.
Explanation:
Because multitasking is the process of an operating system in which provides users to accomplish more than one jobs at the same time, for example, we can listen music with creating documents in word such as we can do multiple jobs at a time by which we can save much more time to do other works. So, that's why the following option is correct.
Recall the problem of finding the number of inversions. As in the text, we are given a sequence of numbers a1, . . . , an, which we assume are all distinct, and we define an inversion to be a pair i < j such that aj < ai . We motivated the problem of counting inversions as a good measure of how different two orderings are. However, one might feel that this measure is too sensitive. Lets call a pair a significant inversion if i < j and 2aj < ai .
(a) Describe a O(n log n) algorithm to count the number of significant inversions between two orderings. Make clear how is it that your algorithm would achieve the given O(n log n) execution time bound.
Answer:
The algorithm is very similar to that of counting inversions. The only change is that here we separate the counting of significant inversions from the merge-sort process.
Explanation:
Algorithm:
Let A = (a1, a2, . . . , an).
Function CountSigInv(A[1...n])
if n = 1 return 0; //base case
Let L := A[1...floor(n/2)]; // Get the first half of A
Let R := A[floor(n/2)+1...n]; // Get the second half of A
//Recurse on L. Return B, the sorted L,
//and x, the number of significant inversions in $L$
Let B, x := CountSigInv(L);
Let C, y := CountSigInv(R); //Do the counting of significant split inversions
Let i := 1;
Let j := 1;
Let z := 0;
// to count the number of significant split inversions while(i <= length(B) and j <= length(C)) if(B[i] > 2*C[j]) z += length(B)-i+1; j += 1; else i += 1;
//the normal merge-sort process i := 1; j := 1;
//the sorted A to be output Let D[1...n] be an array of length n, and every entry is initialized with 0; for k = 1 to n if B[i] < C[j] D[k] = B[i]; i += 1; else D[k] = C[j]; j += 1; return D, (x + y + z);
Runtime Analysis: At each level, both the counting of significant split inversions and the normal merge-sort process take O(n) time, because we take a linear scan in both cases. Also, at each level, we break the problem into two subproblems and the size of each subproblem is n/2. Hence, the recurrence relation is T(n) = 2T(n/2) + O(n). So in total, the time complexity is O(n log n).
Correctness Proof: We will prove a stronger statement that on any input A our algorithm produces correctly the sorted version of A and the number of significant inversions in A. And, we will prove it by induction. Base Case: When n = 1, the algorithm returns 0, which is obviously correct.
Inductive Case: Suppose that the algorithm works correctly for 1, 2, . . . , n − 1. We have to show that the algorithm also works for n. By the induction hypothesis, B, x, C, y are correct. We need to show that the counting of significant split inversions and the normal merge-sort process are both correct. In other words, we are to show that z is the correct number of significant split inversions, and that D is correctly sorted.
First, we prove that z is correct. Due to the fact that B and C are both sorted by the induction hypothesis, for every C[j], where j = 1, . . . , length(C), we can always find the smallest i such that B[i] > 2C[j]. Therefore, B[1], B[2], . . . , B[i − 1] are all smaller than or equal to 2C[j], and B[i], B[i + 1], . . . , B[length(B)] are all greater than 2C[j]. Thus, length(B) − i + 1 is the correct significant split inversion count for pairs involving C[j]. After counting the number of correct significant split inversions for all C[j], where j = 1, . . . , length(C), z is the correct number of significant split inversions. Second, we show that D is the sorted version of A.
This is actually the proof of merge-sort. Each time, we append one element from B or C to D. At each iteration k, since B and C are both sorted by the induction hypothesis, min(B[i], C[j]), the one to be appended to D, is also the smallest number among all the numbers that have not been added to D yet.
As a result, every time we append the smallest remaining element (of B and C) to D, which makes D a sorted array
UC is importing 1000 records and want to avoid duplicate, how can they do it?
Answer:
By unchecking the 'allow duplicate' box and checking the 'Block duplicate' box in the SalesForce user interface. More also, including a column in the import file that has other record name(SF ID) will ensure no duplicate during import.
Explanation:
importing 1000 records is quiet lengthy and to avoid duplicate it is important to include in the import file that has other record name(SF ID). By including a column that has another file ID every record will be referenced uniquely thereby easily identifying any duplicate.
It is also important to check the ''Block duplicate' box in the salesForce user interface to ensure that records are imported without duplicate.
John is runnig his Database application on a single server with 24 Gigabytes of memory and 4 processors. The system is running slow during peak hours and the diagnostic logs indicated that the system is running low on memory. John requested for additional memory of 8 Gigabytes to be added to the server to address the problem. What is the resultant type of scaling that John is expecting?
Answer:
Vertical Scaling
Explanation:
Vertical scaling means the ability to increase the capacity of existing hardware or software by adding resources. In this case, more GB is added (8GB) to the server to address the problem. So vertical scaling is the resultant type john is expecting.

Explanation:
As the network engineer, you are asks to design an IP subnet plan that calls for 5 subnets, with the largest subnet needing a minimum of 5000 hosts. Management requires that a single mask must be used throughout the Class B network. Which of the following is a public IP network and mask that would meet the requirements?a. 152.77.0.0/21b. 152.77.0.0/17c. 152.77.0.0/18d. 152.77.0.0/19
Answer:
d) 152.77.0.0/19 (255.255.224.0)
Explanation:
If it is required to use a single mask throughout a Class B network, this means that by default, we have 16 bits as network ID, and the remaining 16 bits as host ID.
If we need to set up 5 subnets and we need that the largest subnet can support a minimum of 5000 hosts, we need to divide these 16 bits from the Host ID part, as follows:
Number of hosts = 5000
We need to find the minimum power of 2 that meet this requirement:
2ˣ - 2 = 5,000 ⇒ x = 13
We have left only 3 bits from the original 16, and repeating the process, we find that we need to use the 3 bits in order to accommodate the 5 subnets,
due to with 2 bits we could only support 4.
So, we need that the address mask be, using the CIDR notation, /19, as we need that the first three bits from the third byte to be part of the network ID.
In decimal notation, it would be as follows:
255.255.224.0
The correct IP subnet plan that can support at least 5000 hosts in the largest subnet while using a Class B network and a single mask throughout is 152.77.0.0/19.
Explanation:You are asked to provide an IP subnet plan for a scenario that requires 5 subnets, with the largest subnet supporting at least 5000 hosts, while using a single mask throughout a Class B network. To determine the correct subnet mask, you need to consider the number of hosts required for the largest subnet. Given that each subnet needs to accommodate at least 5000 hosts, the subnet must allow for more than 5000 host addresses. Calculating the number of bits for the host part, 2n - 2 must be greater than 5000 (where n is the number of host bits). This calculation gives us at least 13 bits for the host part (213 - 2 = 8190). Therefore, considering a Class B address starts with 16 network bits, adding 13 bits for the host part totals 29 bits for the network and host. Therefore, the subnet mask should be /19 (32 - 13 = 19) to meet the requirements.
With this in mind, among the given options, 152.77.0.0/19 is the correct network and mask that would meet the requirements as it provides up to 8190 possible host addresses in each subnet, which is more than sufficient for the largest subnet that requires 5000 hosts.

int[] num = new int[100];for (int i = 0; i < 50; i++)num[i] = i;num[5] = 10;num[55] = 100;What is the index number of the last component in the array above?1. 992. 1003. 04. 101
Answer:
1. 99
Explanation:
As the array is declared with space of 100 integers, 100 integers' space will be allocated to variable num. Moreover, Index number of last component is always the length - 1 because array's index start with 0 and ends till length-1. As array will initialize all the remaining spaces with garbage value so they will be displayed if accessed through num[index] where index s the index number to be displayed.
As size of array is 100. So, 99 will be the index of the last component of the array.

File Letter Counter
Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Use Notepad or another text editor to create a sample file that can be used to test the program.
The C++ program prompts the user for a file name and a character, counts the occurrences of the character in the file, and displays the result. Error handling is included.
Below is a simple C++ program that accomplishes the task described:
```cpp
#include <iostream>
#include <fstream>
using namespace std;
int main() {
string fileName;
char targetChar;
cout << "Enter the name of the file: ";
cin >> fileName;
cout << "Enter the character to count: ";
cin >> targetChar;
ifstream inputFile(fileName);
if (!inputFile) {
cerr << "Error opening file. Make sure the file exists." << endl;
return 1;
}
int charCount = 0;
char currentChar;
while (inputFile.get(currentChar)) {
if (currentChar == targetChar) {
charCount++;
}
}
cout << "The character '" << targetChar << "' appears in the file " << charCount << " times." << endl;
inputFile.close();
return 0;
}
```
This program prompts the user to enter a file name and a character. It then opens the specified file, counts the occurrences of the specified character, and displays the result. If the file is not found, it provides an error message.

The subject at hand revolves around the creation of a computer program for Tom's Athletic Club to register trainers and their new member enrollments. The application would collect trainer names and the count of their respective enrollments, then divide them into categories based on membership numbers. Ultimately, the application would output the number of trainers in every group.
Explanation:The problem describes setting up an application for the needs of a company, specifically Tom's Athletic Club. It implies around a computer program that collects data from user input, in this case, the names of 25 trainers and the number of new members they have enlisted for the year. The output that the application must produce is a segmentation of the number of trainers based upon the class of members they've registered - 0 to 5, 6 to 12, 13 to 20, or more than 20.
In this scenario, we would write the application in a way that captures and calculates this information. For instance, in Python, we would create lists to store the names of trainers and the respective new members. Further on, using conditional statements, we could sort the trainers into the required groups based on the number of new members enrolled. The result would be the quantity of trainers in each category, which could then be displayed as the result.
This problem combines aspects of data collection, data analysis, and program construction, which are integral components of computer programming and software development processes.

To direct a style rule to specific elements, __________ can be used to match only those page elements that correspond to a specified pattern.
Question 2 options:
a)
web fonts
b)
pseudo-classes
c)
descendant elements
d)
selector patterns
Answer:
d) selector patterns
Explanation:
To apply and create rules to elements in the same class, selector patterns are a simple solution to make the task easier.
Selector patterns allow you to have a set of rules, tools already tested, which allow you to solve most problems directly.
To direct a style rule to specific elements, selector patterns are used. Selectors can be a tag, class, or ID and are specified at the start of a CSS rule followed by curly braces containing the style declarations.
Using Selectors in CSS
To direct a style rule to specific elements, selector patterns can be used to match only those page elements that correspond to a specified pattern. The selector is the first part of a CSS rule that identifies the HTML elements the subsequent styles will apply. It can reference an HTML tag directly, or it can be a custom class, ID or even a combination of selectors for more specificity. Once you specify a selector, you can define styles inside the curly braces {} that follow.
For example, using a descendant selector like .completed ul, you can target all <ul> elements within an element with the class .completed, and apply a specific style such as text-decoration: line-through; to them. This type of specificity ensures that styles are applied precisely to the elements intended. The colon (:) is used in CSS to assign values rather than an equal sign, which is typical in many programming languages.
When defining classes in our CSS file, we precede the name with a period to indicate it is a class and use the class attribute within the HTML document to apply it to elements. Classes allow us to apply different styles to the same type of elements, enhancing the page's design and user experience.
What is the difference between write back and write through?
A. With write back, main memory is updated immediately, but with write through, the memory is updated only when the block is replaced.
B. With write through, main memory is updated immediately, but with write back, the memory is updated only when the block is replaced.
C. With write through, the block is replaced when it is written, but with write back, it is replaced when it is read.
D. With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
E. They are two names for the same thing.
The difference between write back and write through is With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
D. With write through, the block is replaced when it is read, but with write back, it is replaced when it is written.
Explanation:
Write back and write through difference as follows.
Write back update the memory cache at specific intervals times with specific conditions. Memory cache is update on corresponding memory location, which makes faster to desktop or workstation or tablet.
Written through is copied caching techniques data copied to higher level caches. Basically it copy from memory cache only. In write through mode just refresh main memory.
So write back update memory cache on specific intervals whereas write through copy the cache and make memory refresh with fresh updates.

Describe how your leadership and service has made a positive difference in your school, inyour community, in your family and/or on the job, and how it will continue to make adifference in college and beyond.
I could describe my leadership and service as being motivational and more a credit-giver.
I do not own the credit for every successful task that my team has accomplished. In fact, I am giving them all the recognitions they deserved. In times of struggling and great pressure, I would motivate them. Most of their complaints about my leadership method is I do not give importance to time. I normally tend to finish everything before deadlines. With these attitudes, my family learn to adapt to this behavior. They value ideas and teamworks in their respective workplace and like me, they would also hate to submit their works late. They would sometimes get positive feedback from clients for finishing their assigned tasks on time.
A source A producing fixed-length cells is required to use a Token Bucket Traffic Shaper (TBTS) of bucket capacity b=20 cell tokens and token feed rate r=40 tokens/sec, followed by a FIFO buffer with output read rate (peak rate) limited to q=120 cells/sec. The output is A’s flow into the network. What is the long-term average cell rate for this flow?
Answer:
Please find the detailed answer as follows:
Explanation:
Long-term average cell rate is also called as sustained cell rate(SCR). It can be defined as the maximum average cell rate in a log time period(T).
The relation among the SCR, Average cell rate and Peak cell rate is as follows:
Avg.cell rate ≤ SCR ≤ PCR
If the source producing fixed-length cells at constant rate, then the long-term average cell rate will be same as peak cell rate(PCR).

nt[] num = new int[100];for (int i = 0; i < 50; i++)num[i] = i;num[5] = 10;num[55] = 100;What is the value of num.length in the array above?1. 02. 1003. 994. 101
Answer:
Option 2. 100 is correct.
Explanation:
In the above example, we have assigned the value 100 to the array num[] while creating the object of that array.
In the next line, we are assigning the values to the array num[] through the loop which will be executed till less than 50 values as it will be started from 0 but in the next line from that we are getting the total number of elements of that array which will be 100 because length function is used to get the total number of elements in the array which is already assigned as 100.
