描述:
Your task is to Calculate the sum of some integers.
输入:
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.
输出:
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.
