I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.
So below I made a list of leetcode problems that are as close to grokking problems as possible.

As an introduction into Luigi, I am following this tutorial with some modifications, e.g. installation using conda.
The problems and solutions described in the examples below have led to the development of sciluigi,
