题意很简单，但是涉及到的位数非常多，其次是前导零，然后是精度的后导零，给组样例：

0000123.555 000000000000000000000123.55500000000000000000000000000000000000000000

import java.math.BigDecimal;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Scanner cin = new Scanner(System.in);
        while (cin.hasNext()) // 多组输入
        {
            BigDecimal a = cin.nextBigDecimal();
            BigDecimal b = cin.nextBigDecimal();
            if(a.compareTo(b)==0)System.out.println("YES");
            else System.out.println("NO");

        }
    }
