    Hi, I have an idea of a Graph Coloring Game. It's a simple game. The concept is like this: A graph will be given and the user will be asked to colour each of the nodes. If the user is able to colour the graph with the minimum number of colours then the user wins, loses otherwise. I want someone to implement my idea in Java (raw code). Thank you.
