Two undirected simple graphs 
and 
where 
are isomorphic when there exists a bijection 
on V satisfying %2C%20%5Cphi(y)%5C%7D%20%5Cin%20E_1)
if and only if {x, y} ∈ E2.
Given two graphs and , count the number of graphs 
satisfying the following condition:
*
.
* G1 and G are isomorphic.
Given two graphs
*
* G1 and G are isomorphic.
输入描述:
The input consists of several test cases and is terminated by end-of-file.
The first line of each test case contains three integers n, m1 and m2 where |E1| = m1 and |E2| = m2.
The i-th of the following m1 lines contains 2 integers ai and bi which denote {ai, bi} ∈ E1.
The i-th of the last m2 lines contains 2 integers ai and bi which denote {ai, bi} ∈ E2.
输出描述:
For each test case, print an integer which denotes the result.
示例1
输入
3 1 2 1 3 1 2 2 3 4 2 3 1 2 1 3 4 1 4 2 4 3
输出
2 3
备注:
* 1 ≤ n ≤ 8
*
* 1 ≤ ai, bi ≤ n
* The number of test cases does not exceed 50.
