Question
Consider the following rooms from a hotel:
D2
Room 217
Room 218
D1
D3
Hallway
D6
D4
Room 318
Room 317
D5
A. Please draw a graph that shows how the various rooms are connected to each-other by
doorways (count the Hallway as a normal room)
B. Please give a walk from room 217 to room 318 that is not a trail.
c. Is there an Euler circuit through these rooms? 1.e., is it possible to walk around the rooms,
starting and ending in the same room, and visiting every room while passing through each
door exactly once? Please give such a circuit, if one exists, or say how you know that no
such circuit exists.
