Case study: remove k digits - a depth first search approach

Dec. 10, 2019

Introduction

It was my mock interview 10:00 PM on Dec. 9, 2019 as an interviewer. I learned something as an interviewer, and also I like to write a coding blog for this mock interview. It is hard for me to push myself to hold high standard, I need to give out lowest score and learn to use full spectrum from 1 to 4.
