Question

Given s set of n numbers A = [a1, a2, a3,…, an], all sums of the form a1, a1+a2, a1+a2+a3, a1+a2+a3+a4, …, a1+a2+…an is computed in a program. We want to find the number of occurrences of item x in the given set S.

I. Provide a sequential algorithm as a pseudo-code for this problem and explain its running time complexity.

II. Provide a parallel algorithm as a pseudo-code for this problem and explain its running time complexity.
