An Euler circuit is a circuit that uses every edge in a graph with no repeats. Being a circuit, it must start and end at the same vertex. The graph below has several possible Euler circuits. Here’s a couple, starting and ending at vertex A: ADEACEFCBA and AECABCFEDA. The second is shown in arrows.

The start and end nodes have to do one of the two operations. Hence, they'll have an odd degree. Below is an example diagram of Euler path.Algorithm for Euler Circuits 1. Choose a root vertex r and start with the trivial partial circuit (r). 2. Given a partial circuit (r = x 0,x 1,…,x t = r) that traverses some but not all of the edges of G containing r, remove these edges from G. Let i be the least integer for which x i is incident with one of the remaining edges.The start and end nodes have to do one of the two operations. Hence, they'll have an odd degree.
