To print the Euler Circuit of an undirected graph (if it has one), you can use Fleury's Algorithm . This algorithm is () (where E is number of edges). Step 1: Check that the graph has 0 or 2 odd vertices; If there are any other number of odd vertices, no Euler circuit exists In graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex.
