Hi there,
I decided to organize everything I have written so far here so it should be easier to find what you need. I had to postpone some of the chapters for now, so some of the links may not yet work. This will be fixed (soon..)
I. Foundations

II. Sorting and Order Statistics
Chapter 6 Chapter 7 Chapter 8 Chapter 9 Extra Level
III. Data Structures
Chapter 10 Chapter 11 Chapter 12 Chapter 13. Chapter 14 Extra Level
Enjoy!
