Given a list of integers, compute the sum of the nonzero ones.

In the event the list contains no nonzero integers, the desired sum is zero.

Constraints

1 \le N \le 10

-5 \le a_i \le 5

In tests worth 5 marks, all a_i are nonzero.

Input Specification

The first line contains a single integer N.

The next N lines each contain a single integer, a_i, representing the ith integer in the list.

Output Specification

On a single line, output the sum of the nonzero integers.

    A few questions: Why do we get 1G and what's the point of emphasizing non-zero Integers, even if you were to add them, it would't make a difference.
