You are given a set $S=\{1..n\}$. You have to do the following operations until there are no more than $k$ elements left in the $S$:
Firstly, delete the smallest element of $S$, and then randomly delete another $k$ elements one by one from the elements left in $S$ in equal probability.
Note that the order of another deleted $k$ elements matters. That is to say, you delete $p$ after $q$ or delete $q$ after $p$, which are different ways.
For each $i \in [1,n]$, determine the probability of $i$ being left in the $S$.
It can be shown that the answers can be represented by $\frac{P}{Q}$, where $P$ and $Q$ are coprime integers, and print the value of $P \times Q^{-1} \ mod $ $\space 998244353$.
Input
The first line contains the only integer $T(T \in [1,40])$ denoting the number of test cases.
For each test case:
The first line contains two integers $n$ and $k$.
It guarantees that: $n \in [1,5000] ,\ \sum n \in [1,3 \times 10^4],\ k \in [1,5000].$
Output
For each test case, you should output $n$ integers, the $i$-th of them means the probability of $i$ being left in the $S$.
