2019.04.16  Problem DescriptionYour task is to Calculate the sum of some integers. InputInput 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. OutputFor each group of input integers you should output
their sum in one line, and with one line of output for each line in input. Sample Input4 1 2 3 45 1 2 3 4 5
0  Sample Output1015
