Edge Addition BICONT

All submissions for this problem are available.###Read problems statements Hindi , Vietnamese , Mandarin Chinese , Russian and Bengali as well.

You are given a tree with $N$ nodes. For each unordered pair of distinct nodes $(i, j)$ such that there is no edge between nodes $i$ and $j$, we add an edge between these nodes with probability $1/2$.

For each $i$ ($1 \le i \le N$), let $p_i$ be the probability that the resulting graph has exactly $i$ 2-edge-connected components and let $R_i = p_i \cdot 2^{(N-1)(N-2)/2}$. You should compute $R_i$ modulo $10^9+7$ for each $i$ from $1$ to $N$.

Input

Output

Print a single line containing $N$ space-separated integers $R_1, R_2, \dots, R_N$.

Constraints

Subtask #1 (10 points): $1 \le N \le 20$

Subtask #2 (90 points): original constraints

Example Input

3
1 2
2 3

Example Output

1 0 1

Explanation

The only edge that can be added is $(1, 3)$. If this edge is added, there will be one biconnected component; otherwise, there will be three biconnected components. Therefore, $p_1 = p_3 = 1/2$ and $p_2 = 0$.
