Project: NeetCode Blind 75 Solutions

Project background

LeetCode is rather infamous in the programming world. It’s a site where you can solve and practice programming algorithms. There are a lot of problems of varying difficulty. This idea is to try solve the problem in as effecient a way as possible. The skills you learn from these challenges serve you in good stead for later, as many of the principles you learn have broad application.

This project / repo contains my solution to the NeetCode Blind75, which is a small, curate list of LeetCode problems that are commonly asked in interviews.

Why this project

I started the Blind75 for a couple different reasons:

1. I was preparing for interviews, and I wanted to be sharp and have some practice with the kinds of problems that are commonly asked.
2. I am a self-taught developer, and I figured this would be a good way to maybe fill in some gaps when it comes to data structures and algorithms (DSA).
3. They’re kinda fun actually.

I figured if I’m going to be doing these problems, I’d might as well make it visible. So instead of just keeping the code on Neet- / LeetCode, I would put it in my own repository, where I own it and can also have multiple solutions to the same problem.

Languages

You can solve the problems in many different languages on the Neet- / LeetCode website. I opted for Python initially, as it’s very direct and you are able to really focus on the algorithmic thinking rather than issues of memory management etc.

I took a break from this project for a while (I got finished the Linked List group, ~30% of the problems), and when I came back to it after a few months I decided to begin again with Java. Once I’ve caught up to where I am with Python, I’ll switch back to Python and continue.

This is a living repo, and I am adding solutions occassionally. I’m also blogging about some of the problems.
