62. Each of the accompanying graphs represent the
sidewalks to be cleaned in a fancy garden (one pass over
a sidewalk will clean it). Can the cleaning be done using
an Euler circuit? If so, show the circuit in each graph by
numbering the edges in the order the Euler circuit uses
them. If not, explain why no Euler circuit is possible.

Expert Solution
Step 1

An Euler circuit is a circuit that uses every edge of a graph exactly once. An Euler path starts and ends at different vertices. An Euler circuit starts and ends at the same vertex.
