# Totient Extreme

Given the value of **n**, you will have to find the value of **H**. The meaning of **H** is given in the following code:

Totient or phi function, **φ**(**n**) is an arithmetic function that counts the number of positive integers less than or equal to **n** that are relatively prime to **n**. That is, if **n** is a positive integer, then **φ**(**n**) is the number of integers **k** in the range **1** ≤ **k** ≤ **n** for which **gcd**(**n**, **k**) = **1**.

#### Input

The first line contains the number of test cases **t** (**0** < **t** ≤ `10`

). It is followed by ^{6}**t** lines each containing a number **n** (**0** < **n** ≤ `10`

).^{4}

#### Output

For each line produce one line that contains the value of **H** for the corresponding **n**.
