📌 Before starting to use this resource, it is important that you’ve completed TIP101 or have a strong grasp on programming fundamentals (e.g. data types, syntax, conditionals, loops)

How to use this resource

If you already have a strong grasp of programming fundamentals, we recommend following this guide in the suggested order. Each section begins with a concise overview of a data structure or algorithm, followed by detailed LeetCode problem walkthroughs, covering time and space complexities and solution trade-offs. You'll then apply these concepts through additional LeetCode problems, mainly at the easy or medium level, though you can explore more on the platform for extra practice. Most interview questions are medium difficulty, so that’s where you should focus—but feel free to tackle harder questions if you’re up for it. Good luck!
