(3) Give Big-O bounds, in terms of n, for the worst-case running times of each of the code fragments below. In each case, assume that A and B are arrays of integers. You should formally derive the running times of each algorithm and then give the Big-O result (it does not suffice to merely state running times or give high-level explanations of running times). (a) /* assume equal-length arrays */ in = A.length 2 count = 0 3 for i=1 to n - 1 do 4 | total = 0 for j = 0 to n - 1 do for k=0 to j do I total = total + A[k] if B[i] == total then count++ 10 return count in= A.length 2 count = 0 3 for i=1 to n do 4 j=1 while j
