Problem Statement

You are given positive integers NN and MM. For each k=1,,Nk=1,\ldots,N, solve the following problem.

  • Problem: We will divide NN people with ID numbers 11 through NN into kk non-empty groups. Here, people whose ID numbers are equal modulo MM cannot belong to the same group. How many such ways are there to divide people into groups? Since the answer may be enormous, find it modulo 998244353998244353.

Here, two ways to divide people into groups are considered different when there is a pair (x,y)(x, y) such that Person xx and Person yy belong to the same group in one way but not in the other.

Constraints

  • 2N50002 \leq N \leq 5000
  • 2MN2 \leq M \leq N
  • All values in input are integers.

Input

Input is given from Standard Input in the following format:

NN MM

Output

Print NN lines.

The ii-th line should contain the answer for the problem with k=ik=i.

People whose ID numbers are equal modulo 22 cannot belong to the same group. That is, Person 11 and Person 33 cannot belong to the same group, and neither can Person 22 and Person 44.

  • There is no way to divide the four into one group.
  • There are two ways to divide the four into two groups: {{1,2},{3,4}}\{\{1,2\},\{3,4\}\} and {{1,4},{2,3}}\{\{1,4\},\{2,3\}\}.
  • There are four ways to divide the four into three groups: {{1,2},{3},{4}}\{\{1,2\},\{3\},\{4\}\}, {{1,4},{2},{3}}\{\{1,4\},\{2\},\{3\}\}, {{1},{2,3},{4}}\{\{1\},\{2,3\},\{4\}\}, and {{1},{2},{3,4}}\{\{1\},\{2\},\{3,4\}\}.
  • There is one way to divide the four into four groups: {{1},{2},{3},{4}}\{\{1\},\{2\},\{3\},\{4\}\}.
