OJ中循环处理多组输入数据

输入描述:

输入包括两个正整数a,b(1 <= a, b <= 1000),输入数据包括多组。

 

python

import sys
for line in sys.stdin:
    a = line.split()
    print(int(a[0])+int(a[1]))




while True:
    try:
        a = input().split()
        print(int(a[0]) + int(a[1]))
    except:
        break

 

 

java

import java.util.Scanner;
 
// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        // 注意 hasNext 和 hasNextLine 的区别
        while (in.hasNextInt()) { // 注意 while 处理多个 case
            int a = in.nextInt();
            int b = in.nextInt();
            System.out.println(a + b);
        }
    }
}

 

import java.io.BufferedReader;
import java.io.InputStreamReader;
 
public class Main {
   public static void main(String[] strr) throws Exception {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String str = null;
        while ((str=br.readLine())!=null){
            String[] nums = str.split(" ");
            int a = Integer.parseInt(nums[0]);
            int b = Integer.parseInt(nums[1]);
            System.out.println(a+b);
        }
    }
}
