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NOAC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
