Leetcode discuss: 3. Longest Substring Without Repeating Characters

Here is my post. 

C# My showcase of learning starting from 2015 April

  1. Longest Substring Without Repeating Characters
    June 24, 2020
    Introduction
    It is my most favorite algorithm to review. I had docusign phone interview in Oct. 2019 to work on similar algorithm, and then I have one hour onsite in January 2015 with Facebook in the city of Vancouver to work on this sliding window algorithm.

It took me hours to work on the algorithm back in April 2015. On June 24, 2020, it only took me less than 15 minutes to write and test code and make sure it is bug free.

I like to add some review comments on my practice in 2015 as well.
