I need to write the following code taking entera from the user. ### Java Program to Check a Magic SquareA magic square is an $ N \times N $ matrix where the sums of each row, each column, and the two diagonals add up to $ N(N^2 + 1)/2 $, which is known as the magic number. Each matrix entry is a unique number from 1 to $ N^2 $.The following outlines the process to create a program that determines if a 4 $\times$ 4 matrix is a magic square:1. **Define the Matrix**: Initialize the matrix and generalize the rows and columns using variables entered by the user.2. **Calculate the Magic Number**: Compute the magic number using the formula $ N(N^2 + 1)/2 $.3. **Row and Column Sum Calculations**: Implement separate functions to compute the sums of each row and each column. Ensure these sums match the magic number.4. **Diagonal Sum Calculation**: Create a function to calculate the sums of the diagonals, verifying that these also match the magic number.5. **Display Results**: The program will output the matrix and a message indicating whether or not it is a magic square.

The answer to thee following question:-Java Code:- import java.util.Scanner;public class Main { public static void Sum(int a[][]) { for (int i = 0; i < 4; i++) { int sumRow = 0; for (int j = 0; j < 4; j++) { sumRow = sumRow + a[i][j]; } System.out.println("Sum of " + (i + 1) + " row:" + sumRow); } for (int i = 0; i < 4; i++) { int sumCol = 0; for (int j = 0; j < 4; j++) { sumCol = sumCol + a[j][i]; } System.out.println("Sum of " + (i + 1) + " column:" + sumCol); } } public static void DiagonalSum(int a[][]) { int sum=0; for(int i=0;i<4;i++) { for(int j=0;j<4;j++) { if(i==j) //this condition checks for diagonal { sum = sum + a[i][j]; } } } System.out.println("SUM of DIAGONAL elements of the matrix = "+sum) ; } static boolean isMagicSquare(int mat[][]) { int sumd1 = 0,sumd2=0; for (int i = 0; i < 4; i++) { sumd1 += mat[i][i]; sumd2 += mat[i][4-1-i]; } if(sumd1!=sumd2) return false; for (int i = 0; i < 4; i++) { int rowSum = 0, colSum = 0; for (int j = 0; j < 4; j++) { rowSum += mat[i][j]; colSum += mat[j][i]; } if (rowSum != colSum || colSum != sumd1) return false; } return true; } public static void main(String[] args) { int array[][] = new int[4][4]; Scanner sc = new Scanner(System.in); System.out.println("Enter the elements of the array: "); for (int i = 0; i < 4; i++) for (int j = 0; j < 4; j++) array[i][j] = sc.nextInt(); System.out.println("Elements of the array are: "); for (int i = 0; i < 4; i++) { for (int j = 0; j < 4; j++) System.out.print(array[i][j] + " "); System.out.println(); } Sum(array); DiagonalSum(array); if (isMagicSquare(array)) System.out.println("Magic Square"); else System.out.println("Not a magic" + " Square"); }} Output:-

(Physics: acceleration) Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: a = (v1 - v0) / t Here, v0 is the starting velocity in meters per second, v1 is the ending velocity in meters per second, and t is the time span in seconds. Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration. Class Name: Exercise01_02Extra
(Game: ATM machine) Use the Account class created in our previous Lab Exercise to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . ., 9, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.
You are awesome! Could you do these too please? Q4: Create a function that multiply's two numbers together and outputs the answer. The function must accept 2 parameters. Don't forget about SCOPE if you're using varibles inside of your function. Q5: Using your multiply function, use the shortest amount of code to display the following output on the screen: 1 * 1 = 1 2 * 2 = 4 3 * 3 = 9 4 * 4 = 16 5 * 5 = 25 6 * 6 = 36 7 * 7 = 49 8 * 8 = 64 9 * 9 = 81 10 * 10 = 100 Q6: Determine using a conditional statement, if the following variable is a number or is not not a number. If it is not, try to convert it to a number and use your mult() function to multiply it by 2. NOTE: YOU MAY NOT MODIFY ANY VARIBLES that are Constants. const number = "17";
(Intro to Python) Include your name and program output in a comment at the top of the script you submit. Note: upload a script for example scriptname.py (do not copy-paste the interactive mode commands) Write complete code that asks the user to input two integer numbers. Define and call a function called remainder that takes two parameters x and y and prints the remainder when x is divided by y. When y is zero, it should not perform the division and instead print "cannot divide by zero" to prevent the runtime error. Sample output is as follows: Enter a number: x Enter another number: y Remainder of x divided by y is z (you'll fill in the values of x, y and z)
(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…

(Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b ≠ 0. Your program must be menu driven, allowing the user to select the operation (+, –, *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions: Function menu: This function informs the user about the program’s purpose, explains how to enter data, and allows the user to select the operation. Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the…
