Logic Problems: Problem 2

Problem: In an art show, there are 25 galleries as shown. If the entrance is the first arrow to the top left and the exist is the arrow to the bottom right, and each gallery has a door to its adjacent (north, south, east, and west) galleries, then is it possible to go from the entrance to the exist, viewing all of the galleries only once?

Key: Find patterns and color it black and white
