HDOJ 1090 A+B for Input-Output Practice (II)

Problem Description

Your task is to Calculate a + b.

Input

Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.

Output

For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

Sample Input

2

1 5

10 20

Sample Output

6

30

这里有一个输入的限制N，用while或者for循环都可以。

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 a=sc.nextInt();
int b=sc.nextInt();
System.out.println(a+b);
}
}

}

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
for(int i=0;i<n;i++){
int a=sc.nextInt();
int b=sc.nextInt();
System.out.println(a+b);
}
}

}
