A+B for Input-Output Practice
题目描述:
Your task is to calculate the sum of some integers
输入格式:
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
输出格式:
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.
最后一个例题,和之前也看起来差不多,还是多个数字求和,不同的是在输出格式要求多一个空行,如输入:
3
4 1 2 3 4
5 1 2 3 4 5
3 1 2 3
输出:
10
15
6
参考C语言代码:
#include<stdio.h>
int main()
{
int N,M;
int a,sum;
scanf("%d",&N);
while(N--)
{
scanf("%d",&M);
sum=0;
while(M--)
{
scanf("%d",&a);
sum=sum+a;
}
printf("%d\n\n",sum);
}
}
参考C++代码:
#include<iostream>
using namespace std;
int main()
{
int N,M;
int a,sum;
cin>>N;
while(N--)
{
cin>>M;
sum=0;
while(M--)
{
cin>>a;
sum=sum+a;
}
cout<<sum<<endl<<endl;
}
}
参考Java代码:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
int N=sc.nextInt();
while(N--!=0)
{
int M=sc.nextInt();
int sum=0;
while(M--!=0)
{
sum=sum+sc.nextInt();
}
System.out.println(sum);
System.out.println();
}
}
}
参考Python代码:
n = int(input())
for i in range(n):
sum=0
list=input().split()
if list[0]=='0':
break
for i in range(1,len(list)):
list[i]=int(list[i])
sum+=list[i]
print(sum)
print();
以上就是本期内容 基本输入输出也迎来了完结
