An eulerian walk is a sequence of vertices in a graph such that every edge is traversed exactly once. It differs from an eulerian circuit in that the starting and ending vertex don’t have to be the same. Prove that if a graph is connected and has at most two vertices of odd degree, then it has an eulerian walk.

Show that a graph without isolated vertices has an Eulerian walk if and only if it is connected and all vertices except at most two have even degree.

Determine whether the following statement about graph theory is true or false. (1) If a graph with m vertices is connected, then there must be at least m-1 edges. (2) If a graph with m vertices has at least m−1 edges, then the graph must be connected. (3) A simple undirected graph must contain a cycle, if it has m vertices with at least m edges. (4) A graph must contain at least m edges, if it has m vertices...

Give an algorithm to detect whether a given undirected graph contains a cycle. If the graph contains a cycle, then your algorithm should output one. (It should not output all cycles in the graph, just one of them.) The running time of your algorithm should be O(m + n) for a graph with n nodes and m edges.
