Question 4 :Effort (Total Points : 6) Find the effort T(n) as a worst-case for the following procedure: Hint: You can express the effort T(n) as summations. Maxsubvector(a, b) { maxsum for x = 1 to b{ for y = x to b{ sum 0; for z = x to y{ sum += a[z]; } maxsum = max(sum, maxsum); } } I return maxsum; }
