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

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

Input

翻译中…

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

翻译中…

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

Output

翻译中…

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

翻译中…

Note

翻译中…

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

翻译中…

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

翻译中…

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