4. Remove all occurrences of a particular element from an array Consider an array named source. Write a method/function named removeAll( source, size, element) that removes all the occurrences of the given element in the source array. You must execute the method by passing an array, its size and the element to be removed. After calling the method, print the array to show whether all the occurrences of the element have been removed properly. nmm" Use Python Example: source=[10,2,30,2,50,2,2,60,0,0] removeAll(source,8,2) After calling removeAll(source,8,2), all the occurrences of 2 must be removed. Printing the array afterwards should give the output as: [ 10,30,50,60,0,0,0,0,0,0]

Matrix Multiplication• Write a multiplication function that accepts two 2D numpy arrays,and returns the product of the two. This function should test that thearrays are compatible (recall that the number of columns in the firstmatrix must equal the number of rows in the second matrix). Thisfunction should test the array sizes before attempting themultiplication. If the arrays are not compatible, the function shouldreturn -1. solve in python
Sales.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. Now modify the program as follows: Declare an array called sales to save the sales of 5 salespeople. Complete the header of the first for loop. This loop initializes the array. Complete the header of the second for loop. This loop computes the total of array elements. Add code to compute and print the average sale. Add another loop to print the id of each salesperson and the number of their sales. The salespeople are objecting to having an id of 0—no one wants that designation. Modify your program so that the IDs run from 1-5 instead of 0-4. // *************************************************************** // Sales.java // // Reads in and stores sales for each of 5 salespeople. Displays // sales entered by salesperson id and total sales for all salespeople. // // *************************************************************** import java.util.Scanner;…
Find primes This program creates and displays a 5x10 matrix(5 rows and 10 columns) of random integers between 1 and a maximum value(user input). Hint: Use the random library to generate each number and place it into your 2D list. The program then counts the number of prime numbers in each row of the array and displays this number, along with the found primes. The program finally displays the total number of prime numbers in the matrix.
Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

2DArray method:It will allocate a block of memory which represents a two-dimension arraybased on the input values supplied by the user. Ask the user to enter the number of rows andcolumn for 2D array that the user want to manipulate. The number of rows and columns that theuser enters may or may not define a square matrix (when the number of rows equals the numberof columns). The array will have exactly rows time columns (m * n) elements. It will notcontain any extra or empty cells. Initialize the “matrix” by rows with random number between 1to 100. Pass two arguments by out reference so that you can assign the number of row andcolumns of data to the first and second arguments. This is return 2D array method afterallocating new memory for 2D array and initialize it with random value. Generate randomnumber code in C# as following: Random randnum = new Random( );int number = randnum.Next (1, 101);SwapRow method: it will rotate the data in the matrix in an up/down method such that the…
