Solution. Approach: Depth First Traversal can be used to detect cycle in a Graph. DFS for a connected graph produces a tree. There is a cycle in a graph only if there is a back edge present in the graph. A back edge is an edge that is from a node to itself (selfloop) or one of its ancestor in the tree produced by DFS.

Then From that I would get the to find the color that appears the most. In other words, all shades of green will converge to a single green value, all shades of red, blue, black, etc will also converge to a single color value that represents them.
