Hard level algorithm and feelings

Oct. 3, 2018

Introduction

I choose to work on easy level algorithms since this July 2018. I never feel so relax and enjoyable last three months.

Today I had chance to review some of hard level algorithms. I learn that the algorithm can get so complicated. I better learn one thing  a time for multiple easy level algorithms.

Get smart on learning 

It can make big difference to choose good strategy to practice Leetcode algorithms.
