For a prime number $$$n$$$, if a pair of positive integers $$$(x, y)$$$ satisfies the congruence relation: $$$$$$x^y\equiv y^x \pmod n.$$$$$$ Then we consider $$$(x, y)$$$ to be magical.
We want to know how many ordered pairs of positive integers $$$(x, y)$$$ are magical for a given prime number $$$n$$$, where $$$0 \lt x, y \le n^2 - n$$$. Since the answer could be large, we will output it modulo 998244353.
The first line input a positive integer $$$T$$$ $$$(1\le T \le 10)$$$, which represents the total number of test cases.
Then for each test case, input a single line with a prime number $$$n$$$ $$$(2\le n \le 10^{18})$$$, and it's guaranteed that $$$n-1$$$ is not a multiple of $$$998244353$$$.
Output $$$T$$$ lines, each containing an integer representing the result modulo $$$998244353$$$.
