Problem Statement

We have an NN-sided die where all sides have the same probability to show up. Let us repeat rolling this die until every side has shown up.

For integers ii such that 1iM1 \le i \le M, find the expected value, modulo 998244353998244353, of the ii-th power of the number of times we roll the die.

Definition of expected value modulo $998244353$

It can be proved that the sought expected values are always rational numbers. Additionally, under the constraints of this problem, when such a value is represented as an irreducible fraction PQ\frac{P}{Q}, it can be proved that Q0(mod998244353)Q \neq 0 \pmod{998244353}. Thus, there is a unique integer RR such that R×Q=P(mod998244353)R \times Q = P \pmod{998244353} and 0R<9982443530 \le R < 998244353. Print this RR.

Constraints

  • 1N,M2×1051 \le N,M \le 2 \times 10^5
  • All values in the input are integers.

Input

The input is given from Standard Input in the following format:

NN MM

Output

Print MM lines.

The ii-th line should contain the expected value, modulo 998244353998244353, of the ii-th power of the number of times we roll the die.

For i=1i=1, you should find the expected value of the number of times we roll the die, which is 112\frac{11}{2}.
