HDU 1096 A+B for Input-Output Practice (VIII)
Problem Description
Your task is to calculate the sum of some integers.
Input
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.
Output
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.
Sample Input
3
4 1 2 3 4
5 1 2 3 4 5
3 1 2 3
Sample Output
10
15
6
题意：输入n，代表n组数据，每组数据输入m及m个数，求m个数的和
注意：两组数据之间输出一个空行
#include <stdio.h>int main(){ int n, sum, m, i, a; while (scanf ("%d", &n)!=EOF) { while(n--) { scanf ("%d", &m); sum = 0; for (i=1;i<=m;i++) { scanf ("%d", &a); sum += a; } printf ("%d\n", sum); if(n != 0) printf("\n"); } } return 0;}
