Problem Statement

Snuke found a random number generator.
It generates an integer between 0 and 2^N-1 (inclusive).
An integer sequence A_0, A_1, \cdots, A_{2^N-1} represents the probability that each of these integers is generated. The integer i (0 \leq i \leq 2^N-1) is generated with probability A_i / S, where S = \sum_{i=0}^{2^N-1} A_i. The process of generating an integer is done independently each time the generator is executed.

Snuke has an integer X, which is now 0.
He can perform the following operation any number of times:

Generate an integer v with the generator and replace X with X \oplus v, where \oplus denotes the bitwise XOR.

For each integer i (0 \leq i \leq 2^N-1), find the expected number of operations until X becomes i, and print it modulo 998244353.
More formally, represent the expected number of operations as an irreducible fraction P/Q. Then, there exists a unique integer R such that R \times Q \equiv P \mod 998244353,\ 0 \leq R < 998244353, so print this R.

We can prove that, for every i, the expected number of operations until X becomes i is a finite rational number, and its integer representation modulo 998244353 can be defined.

Constraints

1 \leq N \leq 18

1 \leq A_i \leq 1000

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N
A_0 A_1 \cdots A_{2^N-1}

Output

Print 2^N lines.
The (i+1)-th line (0 \leq i \leq 2^N-1) should contain the expected number of operations until X becomes i, modulo 998244353.

Sample Input 1

2
1 1 1 1

Sample Output 1

4
4

X=0 after zero operations, so the expected number of operations until X becomes 0 is 0.

Also, from any state, the value of X after one operation is 0, 1, 2 or 3 with equal probability.
Thus, the expected numbers of operations until X becomes 1, 2 and 3 are all 4.

Sample Input 2

1 2 1 2

Sample Output 2

0
499122180
4
499122180

The expected numbers of operations until X becomes 0, 1, 2 and 3 are 0, 7/2, 4 and 7/2, respectively.
