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 3 4 1 2 3 4 5 1 2 3 4 5 3 1 2 3

Sample Output 10 15 6

<code>

#include<stdio.h>
#define M 50
void main()
{ int sum[M],a[M],i,k,j,l;
  scanf("%d",&l);
  for(j=0;j<l;j++)
  {  scanf("%d",&i);
   for(k=0;k<i;k++)
     scanf("%d",&a[k]);
  for(sum[j]=0,k=0;k<i;k++)
   sum[j]+=a[k];
  printf("%d\n",sum[j]);
  if(j<l-1)
  putchar('\n');
 }
}
