About this event

What's an algorithm?

Besides being the answer to most interview questions, an algorithm is a way to solve a particular problem in programming.

Google Maps uses an algorithm to calculate driving directions through 3 cities while avoiding highways. Amazon uses an algorithm to figure out exactly what product to recommend to you next so that you'll blindly one-click it.

In this workshop, we will discuss what an algorithm is, introduce the idea of algorithmic complexity (big O notation), demonstrate sort and search algorithms (with a hands-on re-enactment), and finish with an overview of the many types of algorithms out there.

This workshop focuses on design-thinking for algorithms, which is a pre-requisite to expressing these ideas in code. It will be taught by Esther Weon, Full-Stack Software Engineer and Sara Gudeman, Software Engineer at Zillow Group.

A great follow-up workshop to this one is our Whiteboarding Interview Prep ( on Saturday, November 4th!

Topics covered

• Defining an Algorithm

• Data Structures

• Time/space complexity

• Several Sorting Algorithms

• Binary Search

• Algorithms in Real Life



Attendees would benefit from a basic understanding of a programming language, like from JS 101 (, but that is not required.
