WebJun 16, 2024 · There is also provided m colors. The problem is to find if it is possible to assign nodes with m different colors, such that no two adjacent vertices of the graph are of the same colors. If the solution exists, then display which color is assigned on which vertex. Starting from vertex 0, we will try to assign colors one by one to different nodes.
