spoj#SQFREE. Square-free integers

Square-free integers

In number theory we call an integer square-free if it is not divisible by a perfect square, except 1. You have to count them!

Input

First line contains an integer T, the number of test cases (T≤100). The following T lines each contains one positive integer: n, where n ≤ 1014

Output

T lines, on each line output the number of (positive) square-free integers not larger than n.
