Problem Description
ztr loves research Math.One day,He thought about the "Lower Edition" of triangle equation set.Such as $n=x^{2}-y^{2}$.
He wanted to know that ,for a given number n,is there a positive integer solutions?
Input
There are T test cases.
The first line of input contains an positive integer $T(T<=10^{6})$ indicating the number of test cases.
For each test case:each line contains a positive integer ,$n <=10^{18}$.
Output
If there be a positive integer solutions,print $True$,else print $False$
4
6
25
81
105
False
True
True
True
Hint
For the fourth case,$105 = 13^{2}-8^{2}$
