Input

Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to be processed.

输入包含多个测试案例。每一行包含一个整数N，N个整数，然后在同一行。一个测试案例0开始终止输入和测试用例是不能处理。

 

Output

For each group of input integers you should output their sum in one line, and with one line of output for each line in input.

对于每一组输入整数，你应该在一条线和输出，并与输入各占一行输出。

#include<iostream>

			while (i <= n)

				cin >> m;
				sum = sum + m;
				++i;
				
			}
			cout << sum << endl;
