A+B for Input-Output Practice (VIII)

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

34 1 2 3 45 1 2 3 4 53 1 2 3

Sample Output

10156

#include<stdio.h>
int main()
{
 int test,t=0;
 scanf("%d",&test);
 while(test--)
 {
 int s=0,i;
 int n,a[1000];
 scanf("%d",&n);
 for(i=0;i<n;i++)
 {
 if(i==0)
 scanf("%d",&a[i]);
 else
 scanf(" %d",&a[i]);
 s+=a[i];
 }
 t++;
 if(t>1)
 printf("\n");
 printf("%d\n",s);
 }
 return 0;
}
