Prepare for those easy level math algorithms

Sept. 4, 2018

Introduction

It is 11:48 PM. I like to work on those 25 math easy level algorithms. I like to memorize the algorithms before I work on those algorithms as well.

I like to design a drill for me to get comfortable to solve algorithms every day.

I spent time to go over blogs related to keyword search: solve easy level algorithms, and I found the blog that I started to prepare to work on 50 easy level algorithm August 14, 2018. 

From August 14 to Sept 4, 2018, I solved 50 easy level array algorithms.
