This course is intended for professionals that lack formal education in computer science, and that are in search of a simple and practical guide to algorithmic complexity. The course explains the concepts in layman's terms, and teaches how to reason about the complexity of algorithms without requiring one to have an extensive mathematical skillset. This course can also be handy for revising complexity concepts or Big-O analysis before interviews. Finally, the content also scratches the surface of some advanced analysis topics to provide a more encompassing image of the complexity theory.

Big-O Notation For Coding Interviews and Beyond

<p>Finding permutations of a given character or integer array is a common interview problem. Assume we have the following character array of size 4 with no repeating characters, and we need to find out all the permutations of size 4 for the below array.</p>

This chapter shows how one can reason about recursive problems without extensive mathematical knowledge
