这道题目很坑 卡输出格式 要求输出空行,但最后一行不要求多输出,害的我一直WA
这题目的意思就是求几个数的和,开始是代表有几组数据,以后每一行求一次和,然后输出
#include<stdio.h> int main() { int n,m,a; long long sum; while(~scanf("%d",&n)) { int i; for(i=0;i<n;i++) { scanf("%d",&m); sum=0; while(m--) { scanf("%d",&a); sum += a; } printf("%lld ",sum); if(i!=n-1) printf(" "); } } return 0; }
