Your task is to calculate the sum of some integers.
Your task is to calculate the sum of some integers.
Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.
For each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.

#include <iostream> using namespace std; int main() { int N; cin >> N; while (N--) { int M,sum = 0; cin >> M; while (M--) { int i; cin >> i; sum += i; } cout << sum << endl; if (N != 0)cout << endl;//没有此行运行时会出现错误：Presentation Error } return 0; }
