👉 Coloring is a mathematical concept that involves assigning colors to vertices of a graph or graph-like structure. The goal is to find a coloring that ensures every pair of adjacent vertices has different colors, and also guarantees that no two adjacent edges have the same color. In simple terms, a coloring is a method for mapping each vertex in a graph to a unique set of colors. Each color corresponds to a distinct assignment of vertices to its neighbors. The goal is to ensure that each pair of adjacent vertices is
