The problem is this.

After going through the tutorial, and through the discussions, and reading a lot of submitted solutions, I am not exactly able to grasp the concept behind this problem.

I am pretty sure, there's some underlying topic, which I am unaware of.

Can someone please suggest some underlying concepts to better understand this problem? It would be really kind.
