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

 

 

 

 

我的code

#include<stdio.h>
int main(){
int a=0,b=0,sum=0,d;
scanf("%d",&d);
while(d--){
            while(scanf("%d",&a)!=EOF)
            {
                      sum=0;
                      while(a--){
                                     scanf("%d",&b);
                                     sum+=b;
                                 }         
            printf("%d\n",sum);
              if(d)    printf("\n");            
            }
           
  }                           
return 0;
}

 

 

ac  code:

#include <iostream>
using namespace std;
int main()
{
   int n,i,sum,t;
   cin>>t;
   while(t--)
   {
    sum=0;
    cin>>n;
     int *a=new int[n];
  for(i=0;i<n;i++)
  {
   cin>>a[i];
   sum+=a[i];
  }
     cout<<sum<<endl;
  if(t)
      cout<<endl;
   }
}
