HDU 1096
A+B for Input-Output Practice (VIII)
Time Limit: 2000/1000 MS (Java/Others) Memory Limit: 65536/32768 K (Java/Others)
Total Submission(s): 159507 Accepted Submission(s): 48201
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

#include<stdio.h>
int main(void)
{
int n,m,a,sum,i,j;
scanf("%d",&n);
for(i=0;i<n;i++)
{
scanf("%d",&m);
sum=0;
for(j=0;j<m;j++)
{
scanf("%d",&a);
sum+=a;
}
printf("%d\n",sum);
if(i<n-1) printf("\n");
}
return 0;
}
注意:最后一行不能再换行了,这是这道试题容易出错的地方。
