Step 3. Try to find Euler cycle in this modified graph using Hierholzer’s algorithm (time complexity O(V + E) O ( V + E) ). Choose any vertex v v and push it onto a stack. Initially all edges are unmarked. While the stack is nonempty, look at the top vertex, u u, on the stack. If u u has an unmarked incident edge, say, to a vertex w w, then ...

As path is also a trail, thus it is also an open walk. Another definition for path is a walk with no repeated vertex. This directly implies that no edges will ever be repeated and hence is redundant to write in the definition of path. Vertex not repeated Edge not repeated . Here 6->8->3->1->2->4 is a Path . 5.
