Math easy level algorithms

Sept. 11, 2018

Introduction

It is Tuesday evening 9:12 PM. It is time for me to write an easy level algorithm. I still have 18 easy math level algorithms to work on.

One easy level algorithm a day

It is better for me to submit at least one algorithm a day on Leetcode.com.
