Problem Description
Jam has a math problem. He just learned factorization.
He is trying to factorize ax2+bx+c into the form of pqx2+(qk+mp)x+km=(px+k)(qx+m).
He could only solve the problem in which p,q,m,k are positive numbers.
Please help him determine whether the expression could be factorized with p,q,m,k being postive.
Input
The first line is a number T, means there are T(1≤T≤100) cases
Each case has one line,the line has 3 numbers a,b,c(1≤a,b,c≤100000000)
Output
You should output the "YES" or "NO".
Sample Input
