Problem Description
有二个整数,它们加起来等于某个整数,乘起来又等于另一个整数,它们到底是真还是假,也就是这种整数到底存不存在,实在有点吃不准,你能快速回答吗?看来只能通过编程。
例如:
x + y = 9,x * y = 15 ? 找不到这样的整数x和y
1+4=5,1*4=4,所以,加起来等于5,乘起来等于4的二个整数为1和4
7+(-8)=-1,7*(-8)=-56,所以,加起来等于-1,乘起来等于-56的二个整数为7和-8
 

Input
输入数据为成对出现的整数n,m(-10000<n,m<10000),它们分别表示整数的和与积,如果两者都为0,则输入结束。
 

Output
只需要对于每个n和m,输出“Yes”或者“No”,明确有还是没有这种整数就行了。
 

Sample Input
9 15 5 4 1 -56 0 0
 

Sample Output
No Yes Yes
