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

The first line contains a positive integer $T(1\leq T\leq5)$, denoting the number of test cases.
For each test case:
A single line contains a positive integer $a(1\leq a\leq10^9)$.

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