For the test case
5
2 1 2 2 2
The answer has to be 8 because any contiguous subsequence of the array cannot give the sum to be 8.
So from 1 to 9 there are only 8 possible sums(1 to 7 and 9) and hence the answer has to 8.
But the case is not considered in the test cases and the solution giving 8 or 9 both are getting accepted. This is clearly unfair.
So either the submissions has to re-evaluated or the contest has to be unrated.
