Write a function called "AddRows" that accepts two parameters: w1: a matrix of size 7x4 elements of type integer B1: a one dimensional array of size 4. For each column in W1, the function will calculate and store in the corresponding element of array 31, the sum of the elements located in even rows of W1. For example if W1 = 1 4 5 3 1 1 7 6 12 4 9 7 3 6 in 5 8 10 2 10 5 00 8 5 3 4 un 12 12 10 6 Then B1 = 19 35 27 20
