Consider the infinite sequence $s$ of positive integers, created by repeating the following steps:
  Find the lexicographically smallest triple of positive integers $(a, b, c)$ such that   $a \oplus b \oplus c = 0$, where $\oplus$ denotes the bitwise XOR operation.  $a$, $b$, $c$ are not in $s$.  Here triple of integers $(a_1, b_1, c_1)$ is considered to be lexicographically smaller than triple $(a_2, b_2, c_2)$ if sequence $[a_1, b_1, c_1]$ is lexicographically smaller than sequence $[a_2, b_2, c_2]$.  Append $a$, $b$, $c$ to $s$ in this order.  Go back to the first step. 
You have integer $n$. Find the $n$-th element of $s$.
You have to answer $t$ independent test cases.
A sequence $a$ is lexicographically smaller than a sequence $b$ if in the first position where $a$ and $b$ differ, the sequence $a$ has a smaller element than the corresponding element in $b$.
-----Input-----
The first line contains a single integer $t$ ($1 \le t \le 10^5$) — the number of test cases.
Each of the next $t$ lines contains a single integer $n$ ($1\le n \le 10^{16}$) — the position of the element you want to know.
-----Output-----
In each of the $t$ lines, output the answer to the corresponding test case.
-----Example-----
Input

Output

-----Note-----
The first elements of $s$ are $1, 2, 3, 4, 8, 12, 5, 10, 15, \dots $
