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
我的程序如下，但不通过，为什么？
#include <stdio.h>
int main()
{
int n, m, a, sum;
scanf("%d\n", &n);
while(n --)
{
scanf("%d", &m);
sum = 0;
while(m --)
{
scanf("%d", &a);
sum += a;
}
printf("%d\n\n", sum);
}
return 0;
}

#include <stdio.h>

我来回答，好怀念ACM
你英文肯定没学好,这道题目很简单的;
main()
{
int a,b,c,i;
int sum;
while(scanf("%d",&a)!=0)
{
if(scanf("%d",&b)==0) conintue;
else
{
sum=0;
for(i=0;i<b;i++)
{scanf("%d",&c);
sum+=c;
}
printf("%d",sum);
}
}
}
因为题目没对整数大小限制,所以我用了INT 22
