👉 In mathematics, a "retraversed" object is an object that has been traversed (or "revisted") in some way. This means it has undergone some kind of traversal or iteration. For example, consider the graph G = (V,E) where V is the set of vertices and E is the set of edges. The vertices are labeled with integers from 1 to n, where n is the number of vertices in the graph. For each edge u -> v, we
