Analyze each graph below to determine whether it has an Euler circuit and, • If it has an Euler circuit, specify the nodes for one. • If it does not have an Euler circuit, justify why it does not. • If it has an Euler trail, specify the nodes for one. • If it does not have an Euler trail, justify why it does not. b e a f (a)

According to Bartleby guidelines we have to answer only first three question please upload the question separately.

(1):

It has an Euler circuit given below

$c\to d\to f\to a\to b\to c\to a\to d\to e$

(2):

It has Euler circuit because all vertices are even degree
