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

我的答案#include<stdio.h>
int main()
{
int i,a,b,c;
scanf("%d",&a);
for(i=0;i<a;i++)
{
while(scanf("%d",&b)==1)
{
for(i=1;i<=b;i++)
c+=b;
printf("%d\n\n",c);
}
return 0;
}
}

Answer 1

#include<stdio.h>
int main()
{
int i,a,b,c;
scanf("%d",&a);
for(i=0;i<a;i++)
{
while(scanf("%d",&b)==1) //为什么要在循环里放循环？这个while完全多余。
{
for(i=1;i<=b;i++) //这里又是i变量，会导致外循环出错。
c+=b;
printf("%d\n\n",c); //你确定最后一行输出以后还有空行？acm的判断系统要求不差任何一个字符。
}
return 0;
}
