[align=left]Problem Description[/align]
Your task is to calculate the sum of some integers.

 

[align=left]Input[/align]
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.

 

[align=left]Output[/align]
For each group of input integers you should output their sum in one line, and with one line of output for each line in input.

 

[align=left]Sample Input[/align]

此题综合了两种多数据的处理方法。

代码如下：

#include <stdio.h>
int main()
{
int u;
int n;
int t,sum;
scanf ("%d",&u);
while (u--)
{
scanf ("%d",&n);
sum=0; //一定要记得初始化
while (n--)
{
scanf ("%d",&t);
sum+=t;
}
printf ("%d\n",sum);
}
return 0;
}
