For a permutation $p$ of length $n$$^{\text{∗}}$, we define the function:
$$ f(p) = \sum_{i=1}^{n} \lvert p_i - i \rvert $$$$
You are given a number $n$. You need to compute how many distinct values the function $f(p)$ can take when considering all possible permutations of the numbers from $1$ to $n$.
$^{\text{∗}}$A permutation of length $n$ is an array consisting of $n$ distinct integers from $1$ to $n$ in arbitrary order. For example, $[2,3,1,5,4]$ is a permutation, but $[1,2,2]$ is not a permutation ($2$ appears twice in the array), and $[1,3,4]$ is also not a permutation ($n=3$ but there is $4$ in the array).
Input
Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 100$). The description of the test cases follows.
The first line of each test case contains an integer $n$ ($1 \leq n \leq 500$) — the number of numbers in the permutations.
Output
For each test case, output a single integer — the number of distinct values of the function $f(p)$ for the given length of permutations.
Note
Consider the first two examples of the input.
For $n = 2$, there are only $2$ permutations — $[1, 2]$ and $[2, 1]$. $f([1, 2]) = \lvert 1 - 1 \rvert + \lvert 2 - 2 \rvert = 0$, $f([2, 1]) = \lvert 2 - 1 \rvert + \lvert 1 - 2 \rvert = 1 + 1 = 2$. Thus, the function takes $2$ distinct values.
For $n=3$, there are already $6$ permutations: $[1, 2, 3]$, $[1, 3, 2]$, $[2, 1, 3]$, $[2, 3, 1]$, $[3, 1, 2]$, $[3, 2, 1]$, the function values of which will be $0, 2, 2, 4, 4$, and $4$ respectively, meaning there are a total of $3$$$ values.
