HDOJ_ACM 2054 使用java

Problem Description

Give you two numbers A and B, if A is equal to B, you should print "YES", or print "NO".

Input

each test case contains two numbers A and B.

Output

for each case, if A is equal to B, you should print "YES", or print "NO".

Sample Input

1 2 2 2 3 3 4 3

Sample Output

NO

YES

YES

NO

这道题应该考虑到小数，大数，0050，50 等等这些情况 用C语言或者C++会比较麻烦

但是在Java中有 BigDeimal 正好解决这个问题 （ACM可以用JAVA提交）

代码如下：

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");
           }

       }
}
