RATIONAL - Rational Number

Given a number N, find the number of positive irreducible rational numbers less than 1 such that when expressed as P/Q, both P, Q are less than or equal to N.

Input

The first line contain a single integer T, the number of test cases. Following T (<= 1000) lines will contain a test case, a single number N (<= 1000000).

Output

For each test case print the output on a single line.

Example

Input:
3
1
2
3
Output: 0
1
3

given N, we have to find number of irreducible rational numbers of the form P/Q ( < 1 ) and P,Q<=N. For N = 3 (ans=3)--> 1/2 , 1/3 , 2/3. For N = 4 (ans=5)--> 1/2 , 1/3 , 2/3 , 1/4 , 3/4
