Consider summing up the values in a sequence A of n integers, where n is a power of two. Create a new sequence B of half the size of A and set B[i] = A[2i]+A[2i+ 1], fori = 0, 1, ...,(n/2) 1. If B has size 1, then output B[0]. Otherwise, replace A with B, and repeat the process. What is the running time of this algorithm?
