Addition

You are given $N$ natural numbers, each at most 10. Write a program that computes their sum.

The first line contains the number of test cases $T$ ($1 \le T \le 10$). Each test case takes two lines. The first line contains the amount of natural numbers $N$ ($1 \le N \le 100$), and the second line contains the $N$ natural numbers separated by single spaces. Every natural number is at most 10.

For each test case, print the sum of the given natural numbers on a line of its own.
