Solution: Find a Mother Vertex in a Directed Graph

Understand how to find a mother vertex in a directed graph using depth-first search and Kosaraju’s strongly connected component algorithm. Explore step-by-step graph traversal methods, including candidate identification and validation, to grasp the implementation and complexities involved.

We'll cover the following...

Statement

Given a directed graph as input, determine a mother vertex within it. A mother vertex in a graph G=(V,E)G = (V, E), is vertex VV such that all other vertices in GG can be reached by a path from VV. Although a graph might feature multiple mother vertices, your goal is to identify at least one.
