Question:

a) The maximum subsequence sum problem is defined as follows: If $a_1,a_2,...,a_n$ are in Z, find the maximum value $\sum_{k=i}^{j}a_i,$ for all $i,\, j,1\leq i\leq j\leq n.$ We assume that the answer is 0 if all the $a_i$ are negative or if the sum is empty. The following algorithm finds a solution to the problem. Here, we assume that $a_i$ s are stored in the array A.

Maximum-Subsequence $(A,MaxSum)$

1 $Sum\leftarrow 0,MaxSum\leftarrow0$

2 $for\, i\leftarrow1\: to\: n$

3 $do$

4 $Sum=Sum+A[i]$

5 $if$ $Sum>MaxSum$

6 $then$ $MaxSum\leftarrow\, Sum$

7 $else\: if\, Sum<0$

8 $then\, Sum=0$

State precisely a loop invariant for the for loop in line 2–8. Prove that your loop invariant holds and hence conclude that the algorithm works.

b) Analyse the algorithm and find an upper bound for the run time of the above algorithm.
