用C++写太麻烦了，需要考虑各种情况，前导零，后导零，正负数，整数小数。。。
直接用java水过。。。

import java.io.*;
import java.math.*;
import java.util.*;

public class Main {

    public static void main(String[] args) {
        Scanner cin = new Scanner(System.in);
        BigDecimal x, y;
        while(cin.hasNextBigDecimal()){
            x = cin.nextBigDecimal().stripTrailingZeros();
            y = cin.nextBigDecimal().stripTrailingZeros();
            if(x.equals(y))
                System.out.println("YES");
            else
                System.out.println("NO");
        }
    }

}
