My name is khaled, software engineer, blockchain developer and competitive programmer.
In the past i instructed some uni. students in problem solving onsite, prepared some programming (problems&contests) and published online content about programming ~5 years ago(since 2014) and i saw how that helped hundreds of people world wide
International Olympiad in Informatics Training: Path to Gold
This is a 100+ part playbook that takes you from basic C++ programming to a Gold medal at IOI. It has tutorials on 30+ algorithms and data structures, and 75+ problems based on those topics, sorted by increasing difficulty.
This 26-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".

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!
