Madoka is a very strange girl, and therefore she suddenly wondered how many pairs of integers (a,b) exist, where 1≤a,b≤n, for which lcm⁡(a,b)gcd⁡(a,b)≤3.

In this problem, gcd⁡(a,b) denotes the greatest common divisor of the numbers a and b, and lcm⁡(a,b) denotes the smallest common multiple of the numbers a and b.

Input

The input consists of multiple test cases. The first line contains a single integer t (1≤t≤104) — the number of test cases. Description of the test cases follows.

The first and the only line of each test case contains the integer n (1≤n≤108).

Output

For each test case output a single integer — the number of pairs of integers satisfying the condition.


Note

For n=1 there is exactly one pair of numbers — (1,1) and it fits.

For n=2, there are only 4 pairs — (1,1), (1,2), (2,1), (2,2) and they all fit.

For n=3, all 9 pair are suitable, except (2,3) and (3,2), since their lcm is 6, and gcd is 1, which doesn't fit the condition.
