Problem Statement
Takahashi throws $N$ dice, each having $K$ sides with all integers from $1$ to $K$. The dice are NOT pairwise distinguishable. For each $i=2,3,...,2K$, find the following value modulo $998244353$:
- The number of combinations of $N$ sides shown by the dice such that the sum of no two different sides is $i$.
Note that the dice are NOT distinguishable, that is, two combinations are considered different when there exists an integer $k$ such that the number of dice showing $k$ is different in those two.
Constraints
- $1 \leq K \leq 2000$
- $2 \leq N \leq 2000$
- $K$ and $N$ are integers.
Input
Input is given from Standard Input in the following format:
$K$ $N$
Output
Print $2K-1$ integers. The $t$-th of them $(1\leq t\leq 2K-1)$ should be the answer for $i=t+1$.

- For $i=2$, the combinations $(1,2,2),(1,2,3),(1,3,3),(2,2,2),(2,2,3),(2,3,3),(3,3,3)$ satisfy the condition, so the answer is $7$.
- For $i=3$, the combinations $(1,1,1),(1,1,3),(1,3,3),(2,2,2),(2,2,3),(2,3,3),(3,3,3)$ satisfy the condition, so the answer is $7$.
- For $i=4$, the combinations $(1,1,1),(1,1,2),(2,3,3),(3,3,3)$ satisfy the condition, so the answer is $4$.
