ACM-常见注意事项

1、输入、输出必须严格按照题目要求进行，包括空格、换行等

2、输入直到文件结束应该加上循环判断

while(~scanf("%d", &a)){}while(EOF != scanf("%d", &a)){}while(1 == scanf("%d", &a)){}

3、java的输入输出格式

import java.util.Scanner;public class Main {    public static void main(String[] args) {        Scanner in = new Scanner(System.in);        while(in.hasNext()) {        int a = in.nextInt();        int b = in.nextInt();        System.out.println(a + b);        }    }}
