LeetCode - Preface - Day1 (1/1/2020)

LeetCode as routine

I have started LeetCode as a daily routine from New Year's Day of 2020! My daily goal is to solve and write write-ups for 5 questions per day.

Why do I do this routine? The reason is simple. I really wanna pass the coding interview 😂. From my experience of interviews for the Facebook internship (I got rejected at the very final interview though), I learned that explaining the process of how to solve the question is much more important than just solving the questions. So, I have decided to create write-ups in English. (I may omit write-ups for some questions that I solved before.)

My English is obviously ugly even though I live in the U.S. in more than two years, but I hope you guys can understand what I want to say.

If you guys have any questions, let me know!
