Hamiltonian path problem

The Hamiltonian path problem is a well-known problem in graph theory. It involves finding a path in a graph that visits each vertex exactly once. If such a path exists, it is called a Hamiltonian path. In more formal terms: - A **graph** is made up of vertices (or nodes) and edges (connections between nodes). - A **Hamiltonian path** is a path in the graph that includes each vertex exactly once.
