Problem Statement

Find the number, modulo $998244353$, of good sequences of length $N$ whose elements are integers between $0$ and $M$, inclusive, and whose sum is at most $K$.

Here, a length-$N$ sequence $X=(X_1,X_2,\ldots,X_N)$ is said to be good if and only if there is a graph $G$ that satisfies all of the following conditions.

• $G$ is a graph with $N$ vertices numbered $1$ to $N$ without self-loops. (It may have multi-edges.)
• For each $i\ (1\leq i \leq N)$, the degree of vertex $i$ is $X_i$.
• For each $i\ (1\leq i \leq N)$, no edge connects vertex $i$ and vertex $i+1$. Here, vertex $N+1$ means vertex $1$.

Constraints

• $4 \leq N \leq 3000$
• $0 \leq M \leq 3000$
• $0\leq K \leq NM$
• All numbers in the input are integers.
