JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…

1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
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…
