WebWe go over the infamous graph colouring problem, and go over the backtracking solution! WebJan 28, 2024 · Consider m = 3; Output: Return array color of the size V that has numbers from 1 to m. Note that color[i] represents the color assigned to the ith vertex.; Return false if the graph cannot be colored with m colors.; Solution: Naive Approach: The brute force approach would be to generate all possible combinations (or configurations) of colors. WebStart by putting one of the vertexes of the graph on the stack's top. Put the top item of the stack and add it to the visited vertex list. Create a list of all the adjacent nodes of the vertex and then add those nodes to the unvisited at the top of the stack. Keep repeating steps 2 and 3, and the stack becomes empty. first osage baptist church
