What is this?
A collection of 120+ interactive, test-driven Python coding challenges covering algorithms and data structures commonly asked in coding interviews, each delivered as a Jupyter notebook with unit tests and a paired solution notebook, plus an included Anki flashcard deck.
A collection of 120+ interactive, test-driven Python coding challenges covering algorithms and data structures commonly asked in coding interviews, each delivered as a Jupyter notebook with unit tests and a paired solution notebook, plus an included Anki flashcard deck.Is this a book, a tutorial site, or something else?It is a set of Jupyter notebooks: each challenge has a 'challenge' notebook with skeleton code and unit tests for you to fill in, paired with a 'solution' notebook containing a worked, unit-tested implementation.
It is a set of Jupyter notebooks: each challenge has a 'challenge' notebook with skeleton code and unit tests for you to fill in, paired with a 'solution' notebook containing a worked, unit-tested implementation.How do I work through a challenge?Open the challenge notebook for a topic, implement the skeleton function, then run the included unit test, which is expected to fail until your solution is correct; compare against the paired solution notebook if you get stuck.

No, several entries in every category are marked 'Contribute' instead of having a solution, meaning they're still open for community submissions, and the promised on-demand hint feature is listed as not yet available.How are the challenges organized by topic?They're grouped into categories such as Arrays and Strings, Linked Lists, Stacks and Queues, Graphs and Trees, Sorting, Recursion and Dynamic Programming, Mathematics and Probability, Bit Manipulation, Online Judges, System Design, and Object Oriented Design, each with its own challenge count.
