You can't get out of the side you went in

So many ways to go

It's a very simple maze. Yo may enter through any opening and go out also through any exit.

Only two restrictions

  1. While on your way you must not retrace your path.
  2. You can't come out of the side of the maze you went in. In other words, your entry side and exit side must be different.

Three questions

  1. Along how many paths can you walk through the maze?
  2. What is the shortest path?
  3. What is the longest path?

You can form your new questions as well.

Enjoy, it's really simple.
