Course overview
In this course, you’ll learn about recursion, binary trees, binary heaps, and more. By the end, you’ll be able to explain the difference between iteration and recursion, build a binary heap to query large datasets, implement and query a dataset using Binary Search trees, and more.
Best of all, you’ll learn by doing – you’ll practice and get feedback directly in the browser. At the end of the course, you’ll complete a guided project in which you’ll use a B-Tree to implement a key-value datastore in Python.
