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

解：

#include
void main()
{
int n,i,j,t,sum,a,out[1000],q;
sum=0;
scanf(“%dn”,&n);
for (i=0;i<n;i++)
{
scanf(“%d”,&j);
for (t=0;t<j;t++)
{
scanf(“%d”,&a);
sum=sum+a;
out[i]=sum;
}
sum=0;
}
q=n-1;
for (i=0;i<q;i++)
{
printf(“%dnn”,out[i]);
}
printf(“%dn”,out[q]);
}

唔，写的比较麻烦。一开始试提示有格式错误.检查了一下，发现是最后面多了一行空行，RT。

#include
int main()
{
    int a,b,i,j,l[1000],k;
    scanf(“%d”,&i);
    getchar();
    for(j=1;j<=i;j++)
        l[j]=0;
    for(j=1;j<=i;j++)
    {
        scanf(“%d”,&a);
        getchar();
        for(k=1;k<=a;k++)
        {
            scanf(“%d”,&b);
            getchar();
            l[j]+=b;
        }
    }
    for(j=1;j<=i-1;j++)
        printf(“%dnn”,l[j]);
    printf(“%dn”,l[i]);
}
