Learn in Public: Data Structures & Algorithms in Python

・3 min read

I am currently working on becoming more proficient in Data Structures and Algorithms - both for the sake of interviewing and to become a better engineer.

In the following weeks and months, I'll share with you what I've learned along my journey. The content will include:

  • The theory and application of Data Structures & Algorithms.
  • My interviewing experience, tips, and tricks.
  • Fun problems you can solve using what we've learned.

❗️Please share any additional resources that you'd recommend, and topics that I forgot to add in the comments below!

Learning Method

I love learning, but I am not an efficient student. I am great at "consuming" material, like taking courses and going through tutorials. But if you ask me to explain what I've learned, I wouldn't be able to do so. I would say "it just slips my mind", but truth be told I never do the work to commit the material into my long term memory.

This time it is going to be different, and I am going to utilize the following two strategies to improve my retention of what I've learned:

  • Use scientific methods for efficient learning.
  • Following the idea of learning in public, I am going to summarize and share what I'm learning along the way. Learning by teaching makes sure you truly understand the material.

List of Resources

For now, let's start with a summary of resources and a list of topics we'll cover in the following weeks and months.

This is not an exhaustive list of all the resources that are available on the WWW, but rather a list of courses I find intriguing, and the books I own.

Legend to indicate where I'm at:
❗️: Currently working on
βœ…: Done
πŸ’€: Done, but needs a refresher

This is a living list, meaning I'll be coming back and updating it as I work through the material.

Ah the memories. I haven't programmed data structures from scratch since university in the first half of the '90s. I remember the time when, if you wanted a data structure, you had to program it yourself. No fancy libraries or frameworks back then. Not complaining; it was fun even if it drove me nuts. Still nuts. That didn't go away.

I wish you the best of luck and I hope you succeed on your goals and also enjoy the journey. You just encourage me to publicly commit on learning machine learning which is something I have been trying but not really commiting for a couple of months. πŸ€“

Thank you! I hope you'll get started with learning ML and will write about it. Studying ML is also on my to do list, it'd be a great addition to read about your journey :)
