980. Unique path III

Jan. 21, 2019

Introduction



It is hard level algorithm. I like to start to work on hard level algorithm in weekly contest even after the contest. I like to challenge myself and push myself to learn and keep myself competitive.

My practice


Here is my practice.

Actionable Items


I need to keep practice hard level algorithms as often as possible. At least I should try to solve one hard level algorithm during one week period. I have not solved a hard level algorithm from Nov. 15 to January 21, 2019 since I work on personal finance research.
