My medium post explaining the challenge: https://medium.com/@alberthu/my-100-day-coding-challenge-1cfc0985b1e5
100 days, 100 computer science interview questions. The questions can range from topics that I'm good at, topics that I know nothing about, different websites like leetcode, geeksforgeeks, interviewcake, codefights, or different Facebook groups I'm a part of. I'll brainstorm solutions, write some code, and discuss tradeoffs. The point is to show up every day and just do it.
