You are given an integer 'N'. Your task is to count the number of integers between 1 and 'N' both inclusive which are coprime to 'N'.
Two numbers are coprime if their greatest common divisor(GCD) is 1.
Here, 1 is considered to be coprime to any number.
If the given integer is 9, then the answer would be 6 Because there are six numbers between 1 and 9 both inclusive which are coprime to 9 i.e 1, 2, 4, 5, 7, and 8.
The first line of input contains an integer 'T' representing the number of test cases or queries to be processed.
Then the test case follows.
The only line of each test case contains an integer 'N'.
For each test case, print a single line containing a single integer denoting the total numbers of integers between 1 and 'N'(both inclusive) which are coprime to 'N', in a single line.
The output of each test case will be printed in a separate line.
You don't have to print anything. It has already been taken care of. Just implement the function.
1 <= T <= 100
1 <= N <= 10 ^ 9

Sample Output 1:
Explanation for Sample 1:
For the first test case, there is only one number which is coprime to 1 i.e 1 itself.
For the second test case, there are only two numbers between 1 and 4(both inclusive) which are coprime to 4 i.e 1 and 3.

Sample Output 2:
Explanation for Sample 2:
For the first test case, there are four numbers between 1 and 12(both inclusive) which are coprime to 12 i.e 1, 5, 7,11.
