Expert Solution
Step 1: Introducing the concept of Hamilton path.

A Hamiltonian path is a concept in graph theory that represents a path in a graph that visits each node (vertex) exactly once. When we encounter a set of nodes and various paths between them, determining a valid Hamiltonian path becomes a puzzle that involves traversing a graph while adhering to certain rules. In the context of the nodes "Fullerton," "LA," "Irvine," "San Diego," and "San Francisco," embark on a journey to discover which sequence constitutes a valid Hamiltonian path. Each step is scrutinized to ensure that no city is revisited and that all cities are visited precisely once. It is a quest for a path that connects these nodes seamlessly, highlighting the essence of Hamiltonian paths in graph theory.
