PROGRAMMING:Hamilton Tour

The famous "Hamilton loop problem" is to find a simple loop that can traverse all the vertices in a graph (that is, each vertex is visited only once). This problem requires you to judge whether any given circuit is Hamilton circuit.
###Input format:
First, the first line gives two positive integers: vertex number $$n $$($$2 < n / Le 200 $$) and edge number $$M $$. This is followed by the $$M $$lines, each of which gives two endpoints of an edge in the format "vertex 1 Vertex 2", where the vertices are numbered from 1 to $$n $. The next line gives a positive integer, $$k $$, which is the number of circuits to be tested. Next, there are $$k $$lines, and each line gives a circuit to be inspected in the following format:
$$n$$ $$V_ 1$$ $$V_ 2$$ $$\cdots$$ $$V_ n$$
Where $$n $$is the number of vertices in the loop, $$V_ I $$is the vertex number on the path.
###Output format:
For each circuit to be inspected, if it is Hamilton circuit, output "yes" in one line, otherwise output "no".
