Problem Description

ztr loves research Math.One day,He thought about the "Lower Edition" of triangle equation set.Such as  n=x2−y2 .

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<=106)  indicating the number of test cases.

For each test case:each line contains a positive integer , n<=1018 .

 

Output

If there be a positive integer solutions,print  True ,else print  False
