Introduction
I like to compare the experience I had on union find algorithms. It is my short research and I like to figure out what I can do in order to master the algorithm.
Comparison study
I like to compare three experience I have so far.
Case 1: Experience on Hackerrank
I worked on union find algorithms again and again on contests, I got over 10 medals. Most of time I had to work on graph algorithm. I applied union find algorithm to solve a few algorithms from 2016 to 2017.
Case 2: 100 minutes work with my ex-coach
I also hired a private coach who gave me a session on union find algorithm. I paid 100 Canadian dollar for 100 minutes session. 10 session I paid $1000 Canadian dollars in less than two weeks.
Case 3: Study top 50 player's submission on Leetcode 947 stones removed on weekly contest 112.
I spent time to study all top 50 player's submission on the algorithm, I learned a few union find algorithm. I spent time to write C# code.
Case 4: Study ranking from 100 to 200 players, I wrote a case study here.
