Country_road solution using algorithms

"Build a looping road through all countries on the map. The road is not allowed to pass through the same country twice. Two squares with a piece of border between them cannot both stay empty. In case there is a number written in a country, this indicates through how many squares in this country the road goes." Algorithms to use : Depth first and Breadth first . I will guide you through out the whole project, I just want you to write 2 functions for this [login to view URL] requested amount will be increased through milestones basic idea of the algorithm will provided during the conversation. link to game : [login to view URL]
