Euler theorem

Problem Description

HazelFan is given two positive integers a,b， and he wants to calculate amodb. But now he forgets the value of b and only remember the value of a, please tell him the number of different possible results.

 

Input

The first line contains a positive integer T(1≤T≤5), denoting the number of test cases.
For each test case:
A single line contains a positive integer a(1≤a≤109).

 

Output

For each test case:
A single line contains a nonnegative integer, denoting the answer.

 

Sample Input

213

 

Sample Output

23
