Slime and Sequences (Easy Version)
Description
Note that the only differences between easy and hard versions are the constraints on $n$ and the time limit. You can make hacks only if all versions are solved.
Slime is interested in sequences. He defined good positive integer sequences $p$ of length $n$ as follows:
- For each $k>1$ that presents in $p$, there should be at least one pair of indices $i,j$, such that $1 \leq i < j \leq n$, $p_i = k - 1$ and $p_j = k$.
For the given integer $n$, the set of all good sequences of length $n$ is $s_n$. For the fixed integer $k$ and the sequence $p$, let $f_p(k)$ be the number of times that $k$ appears in $p$. For each $k$ from $1$ to $n$, Slime wants to know the following value:
$$\left(\sum_{p\in s_n} f_p(k)\right)\ \textrm{mod}\ 998\,244\,353$$
The first line contains one integer $n\ (1\le n\le 5000)$.
Print $n$ integers, the $i$-th of them should be equal to $\left(\sum_{p\in s_n} f_p(i)\right)\ \textrm{mod}\ 998\,244\,353$.
Input
The first line contains one integer $n\ (1\le n\le 5000)$.
Output
Print $n$ integers, the $i$-th of them should be equal to $\left(\sum_{p\in s_n} f_p(i)\right)\ \textrm{mod}\ 998\,244\,353$.

Note
In the first example, $s=\{[1,1],[1,2]\}$.
In the second example, $s=\{[1,1,1],[1,1,2],[1,2,1],[1,2,2],[2,1,2],[1,2,3]\}$.
In the third example, $s=\{[1]\}$.
