HackLand Election – Coding Interview Questions #1

Few days ago, I attended an Android Interview for an MNC where I encountered an interesting coding question – Hackland Election. In this post, I would like to share it with you guys so that it might be helpful for your interview preparations.

Here is the question in the similar lines that was asked during the interview:
