As an exciting puzzle game for kids and girlfriends, the Matches Puzzle Game asks the player to find the number of possible equations $A - B = C$ with exactly $n~(5\le n\le 500)$ matches (or sticks).
In these equations, $A,B$ and $C$ are positive integers. The equality sign needs two matches and the sign of subtraction needs just one. Leading zeros are not allowed.
Please answer the number, modulo a given integer $m~(3\le m\le 2\times 10^9)$.
The input contains several test cases. The first line of the input is a single integer $t$ which is the number of test cases. Then $t~(1\le t\le 30)$ test cases follow.
Each test case contains one line with two integers $n~(5\le n\le 500)$ and $m~(3\le m\le 2\times 10^9)$.
For each test case, you should output the answer modulo $m$.
