Solve the problem.The floor plan of a building is shown in the figure below. Is it possible to start in one of the rooms of the building, walk through each door exactly once, and end up in a different room from the one you started in? (Consider the outside a "room".) Justify your answer.
What will be an ideal response?
No. Each room (including "outside") has an even number of doors. Thus, an Euler path starting and ending in different rooms is not possible.
