Consider the problem of computing the mean m and the variance v of n numbers stored in array A = (a1, a2... an). Here are the expressions to compute m and v m = [sum (a; for i = 1, 2... n)] V = [sum (a2 for i = 1, 2... n) nm]/(n-1) a. Write a pseudo code to compute both m and v which takes the array A as input. The code has to be in one loop. b. What are the loop invariants? c. What is the asymptotic running time of your answer of part a
