Takahashi is in the square $(0, 0, 0)$ in an infinite three-dimensional grid.
He can teleport between squares. From the square $(x, y, z)$, he can move to $(x+1, y, z)$, $(x-1, y, z)$, $(x, y+1, z)$, $(x, y-1, z)$, $(x, y, z+1)$, or $(x, y, z-1)$ in one teleport. (Note that he cannot stay in the square $(x, y, z)$.)
Find the number of routes ending in the square $(X, Y, Z)$ after exactly $N$ teleports.
In other words, find the number of sequences of $N+1$ triples of integers $\big( (x_0, y_0, z_0), (x_1, y_1, z_1), (x_2, y_2, z_2), \ldots, (x_N, y_N, z_N)\big)$ that satisfy all three conditions below.
Since the number can be enormous, print it modulo $998244353$.
Input is given from Standard Input in the following format:

There are three routes ending in the square $(2, 0, -1)$ after exactly $3$ teleports:
1 0 0 0
0
Note that exactly $N$ teleports should be performed, and they do not allow him to stay in the same position.
