Problem Description

Given a number x, ask positive integer  y≥2, that satisfy the following conditions:
1. The absolute value of y - x is minimal
2. To prime factors decomposition of Y, every element factor appears two times exactly.

 

Input

The first line of input is an integer T (  1≤T≤50)
For each test case，the single line contains, an integer x (  1≤x≤1018)

 

Output

For each testcase print the absolute value of y - x

 

Sample Input

5 1112 4290 8716 9957 9095

 

Sample Output

23 65 67 244 70

把x开个根号，相对而言y就是每个素数因子出现一次的数，可以预处理一下10w的素数，然后直接暴力即可
