Suppose that a queue is implemented using a circular array of size 12. What is the value of last after the following operations?
10 enqueue operations
5 dequeue operations
6 enqueue operations
10 dequeue operations
8 enqueue operations
2 dequeue operations
3 enqueue operations
Last = 10

Answers

Answer 1

Answer:

10

Explanation:

An enqueue operation is a function that adds an element(value) to a queue array. A dequeue operations removes an element from a queue array. Queue arrays follow a first-in-first-out approach, so elements that are first stored in the queue are removed/accessed first(enqueue operations add elements at the rear of the queue array).

The following operations leave 10 elements in the queue of array size 12 after its done:

10 enqueue operations= adds 10 elements

5 dequeue operations= removes 5 elements( 5 elements left in queue)

6 enqueue operations= adds 6 elements(11 elements in queue)

10 dequeue operations= removes 10 elements(1 element left in queue)

8 enqueue operations= adds 8 elements(9 elements in queue)

2 dequeue operations= removes 2 elements(7 elements left in queue)

3 enqueue operations= adds 3 elements(10 elements in queue)

Therefore there are 10 elements in the queue after enqueue and dequeue operations.

A majority of the people whose information was compromised are homeless; therefore there is no easy way to contact them in order to alert them of the security breach. How should Data-Time Inc. manage this breach in security

Answers

Incomplete question. Here's the full question:

Data-Time Inc. is a company that manages databases for a large city in Colorado. Included in these databases is information collected from the city’s homeless shelters and free clinics. Specifically, the databases contain personal information of the users of these services over the past 10 years; this includes people’s Social Security numbers and health records.

This data is highly secure and only accessible to the employees of Data-Time Inc. Employees are given a laptop when they are hired which allows them to access the database remotely. Unfortunately, one of these laptops is stolen and the security of the database is compromised.

A majority of the people whose information was compromised are homeless; therefore there is no easy way to contact them in order to alert them of the security breach. How should Data-Time Inc. manage this breach in security?

Explanation:

Since the emphasis is not on reversing the breach that has occurred, but on managing the level of security damage that could occur, it is important measures are directed towards preventing unauthorized access to sensitive information.

For example, the Media Access Control Address (MAC address) of the laptop if known could be greylisted from accessing the server that contains the sensitive information.

Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i

Answers

Answer:

The function is as follows:

int returnsFixed(int arr [],int n){

   int retVal = -1;

   for(int i = 0; i<n;i++){

       if(i == arr[i]){

           retVal = i;

           break;

       }

   }

   return retVal;

}

Explanation:

This defines the functionl it receives the array and the length of the array

int returnsFixed(int arr [],int n){

This initializes the return value to -1

   int retVal = -1;

This iterates through the array

   for(int i = 0; i<n;i++){

This checks if i equals arr[i]

       if(i == arr[i]){

If yes, the return value (i.e. the fixed point) is set to i

           retVal = i;

And the code is exited

           break;

       } This ends the if condition

   } This ends the iteration

This returns the calculated fixed point

   return retVal;

}

Answers

Answer:

The answer is "MPLS".

Explanation:

The MPLS stands for Multiprotocol Label Switching. This packet switching method facilitates the generation of easier personal backbones using a less physical channel, which sends information from one source to its destination with labels rather than IP addresses. Many of these WAN services are sold through huge companies. It is also a technology for data transfer that boosts speed and regulates network traffic flow. The information is directed with this technology via a label rather than needing complicated surveys at every stop in a route cache.

[tex](e)\ "1"23"4"30"7"17[/tex]

Explanation:

Required

Evaluate each expression

The simple rules to follow are:

(1) All expressions in bracket will be evaluated based on its data type

(2) Divisions will return only integer values

(3) Integers immediately after string values will be concatenated (not added)

So, the results are as follows:

[tex](a)\ 4 + 1 + 9 + "." + (-3 + 10) + 11 / 3[/tex]

Evaluate till a string is encountered

[tex]4 + 1 + 9 = 14[/tex]

Followed by "."

Then:

[tex](-3 + 10) = 7[/tex]

[tex]11/ 3 = 3[/tex]

[tex]"." + (-3 + 10) + 11/3 = "."73[/tex] -- because expressions after string operations are concatenated.

So, we have:

[tex]4 + 1 + 9 + "." + (-3 + 10) + 11 / 3 = 14"."43[/tex]

[tex](b)\ 8 + 6 * -2 + 4 + "0" + (2 + 5)[/tex]

Evaluate till a string is encountered

[tex]8 + 6 * -2 + 4 =0[/tex]

[tex]"0" + (2 + 5) ="0"7[/tex]

So, we have:

[tex]8 + 6 * -2 + 4 + "0" + (2 + 5) = 0"0"7[/tex]

[tex](c)\ 1 + 1 + "8 - 2" + (8 - 2) + 1 + 1[/tex]

Evaluate till a string is encountered

[tex]1 + 1 = 2[/tex]

[tex]"8 - 2" + (8 - 2) + 1 + 1 = "8 - 2"611[/tex]

So, we have:

[tex]1 + 1 + "8 - 2" + (8 - 2) + 1 + 1 = 2"8 - 2"611[/tex]

[tex](d)\ 5 + 2 + "(1 + 1)" + 4 + 2 * 3[/tex]

Evaluate till a string is encountered

[tex]5 + 2 =7[/tex]

[tex]"(1 + 1)" + 4 + 2 * 3 = "(1 + 1)"46[/tex] --- multiply 2 and 3, then concatenate

So, we have:

[tex]5 + 2 + "(1 + 1)" + 4 + 2 * 3= 7"(1 + 1)"46[/tex]

[tex](e)\ "1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9)[/tex]

Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.

So, we have:

[tex]"1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9) = "1"23"4"30"7"17[/tex]

The output

The first and second lines initialize num2 to 32 and num1 to 12, respectively.

Next, the remainder is calculated on line 3

[tex]rem = 32\%12[/tex]

[tex]rem = 8[/tex]

Then the while loop is repeated as long as rem > 0.

At first, we have:

[tex]num2 = 32[/tex]

[tex]num1 = 12[/tex]

[tex]rem = 8[/tex]

The first iteration gives:

[tex]num2 = 12[/tex]

[tex]num1 = 8[/tex]

[tex]rem = 12\%8 = 4[/tex]

Is 4 > 0? Yes; The loop is executed again.

This gives:

[tex]num2 = 8[/tex]

[tex]num1 = 4[/tex]

[tex]rem = 8\%4=0[/tex]

Is 0 > 0? No; The loop is executed

The last statement prints the last value of num1;

In the last loop, we have:

Code an operation class called ArrayComputing that will ask user to enter a serials of integers with a loop until -99 is entered and after the input it will keep and display the greatest, the least, the sum and the average of the data entries (-99 is not counted as the data). And code a driver class called ArrayComputingApp to run and test the ArrayComputing class, separately.

Answer:

Explanation:

The following is written in Java and creates the ArrayComputing class. It uses the constructor to create the infinite loop that only breaks when the user enters a -99. After every input number it goes adding the correct values to the variables. Once it is done the user can call any of the getter methods to get the variable values as well as calculate the average.

import java.util.Scanner;

class ArrayComputingApp {

   public static void main(String[] args) {

       ArrayComputing arrayComputing = new ArrayComputing();

       System.out.println("Average: " + arrayComputing.getAverage());

       System.out.println("Greatest: " + arrayComputing.getGreatest());

       System.out.println("Least: " + arrayComputing.getLeast());

       System.out.println("Sum: " + arrayComputing.getSum());

   }

}

class ArrayComputing {

   int greatest, least, sum, average;

   int count = 0;

   Scanner in = new Scanner(System.in);

   public ArrayComputing() {

       while (true) {

           System.out.println("Enter a number or -99 to exit: ");

           int num = in.nextInt();

           if (num == -99) {

               break;

           }

           if (num > this.greatest) {

               this.greatest = num;

           }

           if (this.count == 0) {

               this.least = num;

           } else {

               if (num < this.least) {

                   this.least = num;

               }

           }

           this.sum += num;

           this.count += 1;

       }

   }

   public int getAverage() {

       this.average = sum / count;

       return this.average;

   }

   public int getGreatest() {

       return greatest;

   }

   public int getLeast() {

       return least;

   }

   public int getSum() {

       return sum;

Answer and Explanation:

A spreadsheet is an interactive computer application for the analysis and storage of data. The database is a collection of data and accessed from the computer system. This is the main difference between spreadsheets and databases. The spreadsheet is accessed by the user and the database is accessed by the user. The database can store more data than a spreadsheet. The spreadsheet is used for tasks and used in enterprises to store the data. Spreadsheet and database are two methods and the main difference is the computer application that helps to arrange, manage and calculate the data. The database is a collection of data and organized to access easily. Spreadsheet applications were the first spreadsheet on the mainframe. Database stores and manipulates the data easily. The database maintains the data and stores the records of teachers and courses. The spreadsheet is the computer application and analyzing the data in table form. The spreadsheet is a standard feature for productive suite and based on an accounting worksheet.

Write a Java code statement for each of following:
a) To declare TWO (2) decimal numbers, and ONE (1) whole number.​

Answers

Answer:

double decimal1, decimal2;

int whole;

Explanation:

Required

Declare 2 decimals and 1 int.

The syntax to declare a variable is:

data-type variable-name;

To declare decimal, we simply make use of double or float data types.

So, we have:

double decimal1, decimal2; ----> for the decimal variables

And

int whole; ---- for the whole number

A common problem in parsing computer languages and compiler implementations is determining if an input string is balanced. That is, a string can be considered balanced if for every opening element ( (, [, <, etc) there is a corresponding closing element ( ), ], >, etc).
Today, we’re interested in writing a method that will determine if a String is balanced. Write a method, isBalanced(String s) that returns true if every opening element is matched by a closing element of exactly the same type. Extra opening elements, or extra closing elements, result in an unbalanced string. For this problem, we are only interested in three sets of characters -- {, (, and [ (and their closing equivalents, }, ), and ]). Other characters, such as <, can be skipped. Extra characters (letters, numbers, other symbols) should all be skipped. Additionally, the ordering of each closing element must match the ordering of each opening element. This is illustrated by examples below.
The following examples illustrate the expected behaviour:
is Balanced ("{{mustache templates use double curly braces}}") should return true
is Balanced("{{but here we have our template wrong!}") should return false
is Balanced("{ ( ( some text ) ) }") should return true
is Balanced("{ ( ( some text ) } )") should return false (note that the ordering of the last two elements is wrong)
Write an implementation that uses one or more Stacks to solve this problem. As a client of the Stack class, you are not concerned with how it works directly, just that it does work.

Answers

Answer:

Explanation:

import java.util.*;

public class BalancedBrackets {

// function to check if brackets are balanced

static boolean isBalanced(String expr)

{

Stack<Character> stack = new Stack<Character>();

for (int i = 0; i < expr.length(); i++)

{

char x = expr.charAt(i);

if (x == '(' || x == '[' || x == '{')

{

// Push the element in the stack

stack.push(x);

continue;

}

if (stack.isEmpty())

return false;

char check;

switch (x) {

case ')':

check = stack.pop();

if (check == '{' || check == '[')

return false;

break;

case '}':

check = stack.pop();

if (check == '(' || check == '[')

return false;

break;

case ']':

check = stack.pop();

if (check == '(' || check == '{')

return false;

break;

}

}

// Check Empty Stack

return (stack.isEmpty());

}

public static void main(String[] args)

{

Scanner scan = new Scanner(System.in);

System.out.println("\nEnter the expression to check is balanced or not !");

String expr = scan.nextLine();

boolean output;

output = isBalanced(expr);

System.out.println(output);

if (output)

System.out.println("Balanced ");

else

System.out.println("Not Balanced ");

scan.close();

}

Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.

It will be great if you could explain the answer to me. :)

Answers

Answer:

see your answer in image

mark me brainlist

The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.

Given the following data:

Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.

How to calculate the required disk space?

First of all, we would determine the number of logical records that can be held by each sector as follows:

Number of logical records per sector = 512/120

Number of logical records per sector = 4.3 ≈ 4.0.

Now, we can calculate the required disk space to store 300,000 records:

Disk space = 300,000/4

Disk space = 75,000 sectors.

For the tracks, we have:

Disk space in tracks = 75,000/96

Disk space in tracks = 781.25 ≈ 782.

Disk space in tracks = 782 tracks.

For the surfaces, we have:

Disk space in surfaces = 782/110

Disk space in surfaces = 7.10 ≈ 8.

Disk space in surfaces = 8 surfaces.

The statement that is true about network protocols is that:

Using a protocol other than TCP/IP can result in data loss.

What are network protocols?

A network protocol is a system of principles that governs how data is delivered between devices on the same network.

Primarily, it enables linked devices to interact with one another despite variations in internal operations, architecture, or design.

The way this is done is true the use of Transmission-control protocol/Internet protocol (TCP/IP).

TCP/IP is the primary protocol or communication language of the Internet. Therefore, using a protocol other than TCP/IP can result in data loss.
