Welcoem to posts!!
in the future - u will be able to do some more stuff here,,,!! like pat catgirl- i mean um yeah... for now u can only see others's posts :c
Just launched the first SQL course on NeetCode.
You get to learn PostgreSQL by going through 75+ interactive lessons, where you actually write code to learn concepts.
It covers a lot more than just SELECT .. FROM .. WHERE, including:
- aggregations
- joins
- subqueries
- CTEs
- indexes
- uuids
- pl/pgsql
More courses launching on NeetCode in the next couple months:
1. Unit Testing for Beginners
2. Java for Coding Interviews
3. Python Object Oriented Programming
All NeetCode Pro members automatically get access.

Just updated the NeetCode 150 list of practice problems. Now, each problem includes every possible solution.
Did you know you can invert a binary tree with both DFS and BFS? Well now you do!! π²π²
It includes the time & space for each solution, along with code in [.py, .java, .cpp, .js, .cs]
What languages should I add next?
This is all free btw check it out: neetcode.io/

I finally did it!!
I'm so happy to share that after 6 years of solving leetcode problems, I finally earned enough leet coins to buy myself a leetcode hat.
The next thing I plan on buying is the Big-O notebook. It's only 9900 leet coins, so at this rate I should be able to afford one in 11 years!!
But you know what they say, time flies when you're having fun π

I just finished adding 85 algorithm animations to NeetCode π
They were added to the DSA for Beginners course, which has constantly been improved since launch. (The animation below is shortened & sped up to fit on YT).
Over the last couple months weβve also added:
- Python for Beginners course (82 interactive exercises)
- Python for Coding interviews course (40 interactive exercises)
Over the next few months we plan on adding:
- Animations for Advanced Algorithms course
- Animations for System Design for Beginners course
- Relational Databases course
- Java for Beginners course
- Java for Coding Interviews course
- Python for Object Oriented Programming course
Longer term:
- Advanced System Design course
- Machine Learning course(s)
- Git course(s)
- Parallel Programming course (with interactive lessons)
- Frontend courses (HTML / CSS / JS / TS / React)
And a few other surprises I'll share soon!
Neetcode Pro members will automatically get access to all of it. Doing my best to increase the value of neetcode.io/ each and every day :)

I don't usually make posts when I make courses but I'm really proud of this one: Python for Coding Interviews!
It covers every Python function / lib you'll need for interviews. If you ever saw me do some Python magic in any of my videos, this course will cover it with ~40 interactive coding exercises.
It's the kinda stuff most people learn only after solving 100s of problems with Python, but I think I might be the first person to compile it all in one place.
As always, all NeetCode Pro members automatically have access.
Thereβs nothing i love more than being loyal to my users and constantly providing value to them. :)

Over the next week I will be adding ~100 animations to my Algorithms for Beginners course. Got something else I'm cooking in the lab that's even more exciting, hopefully will share that soon.

The famous German mathematician Carl Gustav Jacob Jacobi once said this:
If you're trying to solve a hard problem, "Invert, always invert".
He wasn't talking about inverting binary trees, he was talking about something so much bigger.
In many programming problems, for example Pacific Atlantic Water Flow ( neetcode.io/problems/pacific-atlantic-water-flow ), the straight-forward solution is not efficient.
But we can apply Jacobi's very simple advice, and attempt to solve the inverse of the problem. Suddenly, we arrive at the optimal solution in a very elegant way.
You would be surprised how often this technique can be applied to coding interview questions.
And even more importantly:
If you think this only applies to math or algorithms, then you should invert that opinion of yours. Because when you start paying attention, you will notice, it applies to everything.

These are the kinds of problem solving techniques I try to teach in my videos :)

I just updated the NeetCode All list from 450 -> 580 problems.
I don't know if I should be proud or embarrassed of making 580 Leetcode videos, but either way.. next stop 1000 πππ

i still can't believe that i literally get to solve leetcode problems for a living. and i honestly wouldn't trade it for anything
