Question: Consider the following algorithm: SUM - ARRAY ( A , n ) 1 sum = 0 2 for i = 1 to n 3 sum

Consider the following algorithm:
SUM-ARRAY(A,n)
1 sum =0
2 for i =1 to n
3 sum = sum + A[i]4 return sum It computes the sum of the n numbers in array A[1: n]. State a loop invariant for the above algorithm, and use its initialization, maintenance, and termination properties to show that the SUM-ARRAY procedure returns the sum of the numbers in A[1: n].
