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
解题思路:把两道题结合了下。
代码如下:
#include <stdio.h>
int main()
{
int a, z, s, n;
int i, sum;
scanf_s("%d", &s);
for (z = 0; z < s; z++)
{
scanf_s("%d", &n);
sum = 0;
for (i = 0; i < n; i++)
{
scanf_s("%d", &a);
sum += a;
}
printf("%d\n", sum);
if (z < s-1)
printf("\n");
else
break;
}
return 0;
}
int main()
{
int a, z, s, n;
int i, sum;
scanf_s("%d", &s);
for (z = 0; z < s; z++)
{
scanf_s("%d", &n);
sum = 0;
for (i = 0; i < n; i++)
{
scanf_s("%d", &a);
sum += a;
}
printf("%d\n", sum);
if (z < s-1)
printf("\n");
else
break;
}
return 0;
}
