Problem Description

Jam has a math problem. He just learned factorization.
He is trying to factorize $ax^2+bx+c$ into the form of $pqx^2+(qk+mp)x+km=(px+k)(qx+m)$.
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 $T(1 \leq T \leq 100 )$ cases

Each case has one line,the line has $3$ numbers $a,b,c (1 \leq a,b,c \leq 100000000)$

Output

You should output the "YES" or "NO".

2
1 6 5
1 6 4

YES
NO

Hint

The first case turn $x^2+6*x+5$ into $(x+1)(x+5)$
