Leetcode 451: Sort Characters By Frequencies

March 19, 2018


I have worked on the algorithm including Leetcode 451 as a subproblem so many times called word count practice.

I am so excited to find at least 10 ideas to solve the algorithm. The practice of the algorithm is to train myself using a few algorithms as small as possible, but I like to exhaust all options of the algorithm, get excited to know various approaches, pro and cons. Therefore, I can apply some ideas to the algorithm I have not met before.

Algorithm practice is coming
