Problem Statement

We have an N-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 i such that $1 \le i \le M,$ find the expected value, modulo 998244353, of the i-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 $\frac{P}{Q}$, it can be proved that $Q \neq 0 \pmod{998244353}.$ Thus, there is a unique integer R such that $R \times Q = P \pmod{998244353}$ and $0 \le R < 998244353$. Print this R.

Input

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

Output

Print M lines.
The i-th line should contain the expected value, modulo 998244353, of the i-th power of the number of times we roll the die.

Constraints

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