Spring 2019: EMP

Most of the slides are similar to Fall 2018. The newer content (problems + some explainations) for the whole semester combined are here.

Fall 2018: EMP

Completely different from the Fall2020 onwards, so it's new content and another chance to review and look over the same concepts again.

More detailed step by step explainations, high effort diagrams, links to leetcode and new problems.
