Fleurys algorithm.

Use Fleury’s algorithm to find an Euler circuit; Add edges to a graph to create an Euler circuit if one doesn’t exist; In the first section, we created a graph of the Königsberg bridges and asked whether it was possible to walk across every bridge once. Because Euler first studied this question, these types of paths are named after him.
