Fox And Travelling

题意翻译

- 给定一张 $n$ 个点 $m$ 条边的无向图。 - 一个点只有当**与它直接相连的点中最多只有一个点未被遍历过时**才可被遍历。 - 询问对于每个 $k \in [0,n]$,遍历 $k$ 个点的方案数。 - $n \le 100$,$m \le \frac{n(n-1)}2$,答案对 $10^9+9$ 取模。

题目描述

Fox Ciel is going to travel to New Foxland during this summer. New Foxland has $ n $ attractions that are linked by $ m $ undirected roads. Two attractions are called adjacent if they are linked by a road. Fox Ciel has $ k $ days to visit this city and each day she will visit exactly one attraction. There is one important rule in New Foxland: you can't visit an attraction if it has more than one adjacent attraction that you haven't visited yet. At the beginning Fox Ciel haven't visited any attraction. During her travelling she may move aribtrarly between attraction. After visiting attraction $ a $ , she may travel to any attraction $ b $ satisfying conditions above that hasn't been visited yet, even if it is not reachable from $ a $ by using the roads (Ciel uses boat for travelling between attractions, so it is possible). She wants to know how many different travelling plans she can make. Calculate this number modulo $ 10^{9}+9 $ for every $ k $ from $ 0 $ to $ n $ since she hasn't decided for how many days she is visiting New Foxland.

First line contains two integers: $ n $ , $ m $ ( $ 1<=n<=100 $ , ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF512D/24ed00a588f4a614b06135ddb4e305abbc097a46.png)), the number of attractions and number of undirected roads. Then next $ m $ lines each contain two integers $ a_{i} $ and $ b_{i} $ ( $ 1<=a_{i},b_{i}<=n $ and $ a_{i}≠b_{i} $ ), describing a road. There is no more than one road connecting each pair of attractions.

Output $ n+1 $ integer: the number of possible travelling plans modulo $ 10^{9}+9 $ for all $ k $ from $ 0 $ to $ n $ .

说明

In the first sample test for $ k=3 $ there are 4 travelling plans: $ {1,2,3},{1,3,2},{3,1,2},{3,2,1} $ . In the second sample test Ciel can't visit any attraction in the first day, so for $ k&gt;0 $ the answer is $ 0 $ . In the third sample test Foxlands look like this: ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF512D/addf9e605d9b5e373ca5aa72327b83279751f9e5.png)
