Race Conditions Studio

Motivation

Race conditions can lead to difficult bugs to find and fix. We gain experience finding them and fixing them.

Background

In this studio, you will take in a collection of strings, clean up each string, and add it into another collection of strings concurrently.

The Core Questions

Really think about these questions in each case. Knowing the answers to these will tell you where the problem is.

• What are the tasks?
• What is the data?
• Is the data mutable?
• If so, how is it shared?
