Web25 apr. 2024 · I have thought about 2 solutions. The first is add bool visited; in vertex or edge struct and initialize it to false, but it just able to use 1 time, because I don't know how to reinitialize the visited. The second approach is make a link list, put the visited vertex in that list and check for visited vertex in that list when required. WebAn *Eulerian circuit* is a closed walk that includes each edge of a graph exactly once. Graphs with isolated vertices (i.e. vertices with zero degree) are not considered to have Eulerian circuits. Therefore, if the graph is not connected (or not strongly connected, for directed graphs), this function returns False.
