這道題應該考慮到小數，大數，0050，50 等等這些狀況 用C語言或者C++會比較麻煩

可是在Java中有 BigDeimal 正好解決這個問題 （ACM能夠用JAVA提交）

代碼以下：

import java.util.*;
import java.math.BigDecimal;

public class Main
{
        public static void main(String args[])
       {
              BigDecimal a,b;
           Scanner in=new Scanner(System.in);
           while(in.hasNextBigDecimal())
           {
                  a=in.nextBigDecimal();
                  b=in.nextBigDecimal();
                  if(a.compareTo(b)==0) System.out.println("YES");
                  else System.out.println("NO");
           }
          
       }
}
