^ MAV 2009 EXAM
Netowkrs question 5

i thought a euler circuit can have 2 odd degrees?
hence why i got b?

so is a euler circuit all even degrees?

also matrices question 6?
i got b
i dont get what the difference between the c and b besides the fraction, explain.

Note: Euler circuit and path are different.

Euler Path uses all edges once, starting at one vertex and ending at another. This is where two odd-degree vertices can be used.

Euler Circuit: uses all edges once, starting and ending at the SAME vertex. All degrees must be even.

thanks, in my notes it had 'euler circuit exactly like euler path except starts and finishes at same vertex' -_-
