Madoka and Strange Thoughts

Madoka is a very strange girl, and therefore she suddenly wondered how many pairs of integers (a,b)(a, b) exist, where 1a,bn1 \leq a, b \leq n, for which $\frac{\operatorname{lcm}(a, b)}{\operatorname{gcd}(a, b)} \leq 3$.

In this problem, gcd(a,b)\operatorname{gcd}(a, b) denotes the greatest common divisor of the numbers aa and bb, and lcm(a,b)\operatorname{lcm}(a, b) denotes the smallest common multiple of the numbers aa and bb.

Input

The input consists of multiple test cases. The first line contains a single integer tt (1t1041 \le t \le 10^4) — the number of test cases. Description of the test cases follows.

The first and the only line of each test case contains the integer nn (1n1081 \le n \le 10^8).

Output

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

Note

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

For n=2n = 2, there are only 44 pairs — (1,1)(1, 1), (1,2)(1, 2), (2,1)(2, 1), (2,2)(2, 2) and they all fit.

For n=3n = 3, all 99 pair are suitable, except (2,3)(2, 3) and (3,2)(3, 2), since their lcm\operatorname{lcm} is 66, and gcd\operatorname{gcd} is 11, which doesn't fit the condition.
