Leetcode weekly contest Sept - Dec 2018 performance review

January 10, 2019

Introduction 

It is important for me to build a good habit to review my performance on weekly contest. I started to play weekly contest again after Sept. 2018, and also I started to study leader board and figure out who are those top performers, how I can learn and improve my performance

My performance

I like to present some statistics on those weekly contests.

My analysis

I like to write down some analysis based on my study. I have 90 minutes to perform four algorithms in the contest, but I never have chance to solve last algorithm.

I still have problems to solve the first easy/ medium level algorithm. Even I can solve the medium level algorithm, it takes me extra time since I am not good enough to find elegant solution in the contest.

I learn a lot in the contest and also after the contest. I hope that I can write next performance review in 3 months with better results.
