Open source algorithm book designed with coding interview at heart

In short, this is a middle-to-high level algorithm book designed with cracking coding interviews at hearts. It offers a one-stop coding interview prep experience. The structure of the book: (1) math and CS theories as coding is not just code after all, (2) Python data structures, (3) algorithm design principles, (4) Classical algorithms explained with core principles. (5) Problem patterns.

Besides trying to make the content easy to follow, here summarize the uniqueness about this book: (1) it offers Python source code that is tailored to be simple so that it would be natural for you to use in interviews (2) all the exercises and examples are from Leetcode problems so that you get to practise online (3) Classical algorithms are explained with design principles. No algorithm is magic. (Check out advanced graph algorithms as an example) (4) problem patterns to help you tackle coding interview questions topic by topic.

The book is still a work in progress, and I have put the more finetuned chapters out to help others in need. I am thinking about opening source the source code of the book(latex) and to go for self-publishing. So far, I have put two year's free time into this side project and will continue to work till it is published. Calling for contributors and feedback!
