NO constraints on the elements of array are given.
Since normal summation is giving wa so it may happen that elements are greater than long long limit.
so use addition like we did in school(carry method) or use big integer.
The answer does fit in long long. Your problem is that you should keep taking input until EOF not only 1 testcase. https://ideone.com/jkCnqF got AC.
oh shit, EOF was the main problem, how can I know which problem i should use EOF?
The input section mentioned "every testcase" which implies the possibility of having more than 1 testcase.
ow, thanks brother
