WebGraph Coloring Problem. Graph coloring (also called vertex coloring) is a way of coloring a graph’s vertices such that no two adjacent vertices share the same color. This post will discuss a greedy algorithm for graph coloring and minimize the total number of colors used. We can color it in many ways by using the minimum of 3 colors.

To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling.

Recursion is a technique that calls the same function again and again until you reach the base case. Backtracking is an algorithm that finds all the possible solutions and selects the desired solution from the given set of solutions.
