Hackerrank: Nominating Group Leaders

April 16, 2017

Introduction

Problem statement: Nominating Group Leaders

It is the first time Julia spent over 2 hours in the week contest to work on an advanced algorithm in 2017.

2 hours Research 

Julia likes to challenge her research ability to work on an advanced algorithm, and try to come out ideas, simple code, and try to break zero - score any point if she can. At 8:47 pm 4/16/2107, there are over 1095 players score more than 8 points, maximum score is 72.

Follow through the discussion, the brute force will be able to score 8 points. It is not a bad idea to come out the brute force solution first.
