Thanks for the explanation Actually I'm not too familar with arrays since I never used them ( seems strange, but thats the truth ) so I guess I need to start dealing with them if I want to achieve the result :) I haven't tried yet, but I suppose that if the graph is smaller should be faster Lets try and see what I'll come up with
