题目描述
This is the easy version of the problem. The only difference between easy and hard versions is the constraint of $m$ . You can make hacks only if both versions are solved.
Chiori loves dolls and now she is going to decorate her bedroom!
As a doll collector, Chiori has got $n$ dolls. The $i$ -th doll has a non-negative integer value $a_i$ ( $a_i < 2^m$ , $m$ is given). Chiori wants to pick some (maybe zero) dolls for the decoration, so there are $2^n$ different picking ways.
Let $x$ be the bitwise-xor-sum of values of dolls Chiori picks (in case Chiori picks no dolls $x = 0$ ). The value of this picking way is equal to the number of $1$ -bits in the binary representation of $x$ . More formally, it is also equal to the number of indices $0 \leq i < m$ , such that $\left\lfloor \frac{x}{2^i} \right\rfloor$ is odd.
Tell her the number of picking ways with value $i$ for each integer $i$ from $0$ to $m$ . Due to the answers can be very huge, print them by modulo $998\,244\,353$ .

输入格式
The first line contains two integers $n$ and $m$ ( $1 \le n \le 2 \cdot 10^5$ , $0 \le m \le 35$ ) — the number of dolls and the maximum value of the picking way.
The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $0 \le a_i < 2^m$ ) — the values of dolls.
The second line contains $n$ integers $a_1, a_2, \ldots, a_n$ ( $0 \le a_i < 2^m$ ) — the values of dolls.
输出格式
Print $m+1$ integers $p_0, p_1, \ldots, p_m$ — $p_i$ is equal to the number of picking ways with value $i$ by modulo $998\,244\,353$ .
