What ds should be used?

#1

I know it’s a graph question, but should I use matrix to store these or an adjacency list.
My question is- should i store the graph in matrix or adjacency list, and should i make the color and size matrix differently?
and that has to be created inside graph class?

you can create a graph using

vector<vector<int>> graph(100005)

Now,
instead of int as data type of element inside the inner vector in graph, you can use other according to your need. Declaring graph like this, gives a lot of options to modify graph according to any problem.

Thanks.
