E - A == B ? HDU - 2054

E - A == B ? HDU - 2054

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 

估计OJ有问题

 

话说 

+0 -0

输出

NO

AC我信了但竟然+1和1.0~N0竟然AC了竟然AC了; 

啊西巴贼烦，下面有WA版改进了添加

+-

号的问题大神帮帮找找BUG。 

这时AC版

本来以为只有正整数没想到还有正负之分所以没包装函数，o(︶︿︶)o 唉后面有时间再修改。各位凑合看,见笑了……
