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. WebIn the backtracking approach to the graph coloring problem, the time complexity is O (m V) O(m^V) O (m V), and space complexity is O(V). The greedy approach to solving the graph coloring problem can be used at most x+1 colors if the maximum degree of a vertex is x. The idea is to color the current vertex with the minimum numbered color that has ...
