Learn Data Structures and Algorithms
Overview

This 28-part course consists of tutorials on data structures and algorithms. It alternates between tutorials and implementation, and you get to implement every algorithm. You can think of this course as a "Free Online Nano Book".

This course teaches algorithms and data structures f...

Why algorithms?

This section introduces the concept of algorithms, and defines what it means when we talk about an algorithm's efficiency.

Your first algorithms!

We'll start with the greedy algorithm, and after that we'll learn about recursion.

Binary search is a recursive search algorithm which runs in O(\log n) time. It's an example of a divide-and-conquer algorithm.

Sorting algorithms

Sorting algorithms are a set of algorithms that all solve the same problem (sorting) but using very different strategies. These algorithms will introduce you to techniques such as recursion, divide-and-conquer, heaps, etc.

If I can solve every single problem of this playlist, does that mean I am well prepared for the coding (just the coding, not prolem solving) of IOI?

Competitive Programmer's Handbook

Hello everyone, wanted to share the Competitive Programmer's Handbook (~300 page PDF). I think reading this book will take you 10x lesser time than Introduction to Algorithms CLRS while teaching you just as much. The book has ~10x lesser words than CLRS and 5x more diagrams (lesser theory and math). Diagrams are very helpful in learning algorithms because it is all about visualization. That is also why this community has a lot of short video tutorials on various algorithms, because visualizing it makes it easy to understand. Enjoy!

Credit to Shiv Pratap Singh for telling me about the handbook.
