Question: 1. Draw six different graphs, each with a different number of vertices. Check to see whether each graph has an Euler circuit or not. Do any of your graphs have an Euler traversal but not an Euler circuit?
2. Draw a graph that has an Euler circuit.
3. Draw a graph that does not have an Euler circuit but does have an Euler traversal.
4. Draw a graph that has neither an Euler circuit nor an Euler traversal.
