WebDefinition 1. A Hamilton's cycle is a graph cycle in which every vertex of a graph is passed only once (except the first vertex). Hamilton's path is a graphical path that visits each vertex exactly once. Finding a Hamilton's cycle with a minimum of edge weights is equivalent to solving the salesman problem. Hamilton's graphs are called Hamilton's. WebA Hamiltonian path, is a path in an undirected graph that visits each vertex exactly once. Given an undirected graph, the task is to check if a Hamiltonian path is present in it or not. Example 1: Input: N = 4,
