I love sharing free resources for learning tech skills, and data structures and algorithms are no exception. One of the best places I've found is Udacity's free course 'Data Structures and Algorithms in Python'. It's beginner-friendly and uses Python, which makes it accessible. Another standout is 'CS Dojo' on YouTube, which breaks down complex topics into easy-to-understand videos.

For those who enjoy reading, the book 'Algorithms Unlocked' by Thomas Cormen is available for free in some university libraries online. It's a lighter version of the famous 'CLRS' and great for self-study.

I’ve been diving into coding for a while now, and free courses with certificates are like hidden gems. Coursera offers some great ones, like 'Data Structures and Algorithms' from UC San Diego, where you can audit for free and pay only if you want the certificate. EdX has similar options, like Georgia Tech’s course, which is top-notch. Khan Academy’s algorithms section is free but doesn’t give certificates. If you’re okay with no certificate, YouTube channels like mycodeschool explain concepts beautifully. I also found freeCodeCamp’s DSA tutorials super practical, though their certificates are for paid members. It’s all about balancing what you need—knowledge or proof.
