HDU1096 A+B for Input-Output Practice (VIII)

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

解题思路：你的任务是计算M个数的和并输出结果。。。注意输出格式。

#include<stdio.h> int main() { int t,n,a,sum; scanf("%d",&t); while(t--) { sum=0; scanf("%d",&n); for(int i=0;i<n;i++) { scanf("%d",&a); sum+=a; } if(t!=0) printf("%d\n\n",sum); else printf("%d\n",sum); } return 0; }
