b. The following is the code for the 3-SUM problem what is the tilde notation for the array access? public static int count(int[] a) { int n = a.length; 0; for (int i = 0; i < n; i++) { int count = %3D %3D for (int j = i+1; j < n; j++) { %3D for (int k = j+1; k < n; k++) { if (a[i] + a[j] + a[k] count++; %3D e) { == } } } } return count; }

Develop python program of function randomArray(m, n) that takes two integers as argument and returns a 2D m-by-n array with random elements in it. Develop python program of function adder(a1, a2) that reads two 2D arrays of the same size and returns an array that is the summation of a1 and a2. To add the two arrays, you need to add their elements, correspondingly. Develop a  python program of function inverseArray(a) that takes a 2D-array as argument and inverses the array. You will need to inverse the rows, first and then inverse the columns, next. For instance, if the array = [[2, 3, 4], [5, 6, 7]], the inverse will be = [[7, 6, 5], [4, 3, 2]]
