Core Patterns
Stacks & queues
Lesson 4 of 5
Two ordering disciplines, last-in-first-out and first-in-first-out, and the problems each one solves.
What you'll learn
- Distinguish last-in-first-out from first-in-first-out and when each fits
- Use a stack to match, parse, and undo
- Reach for a queue when fairness and order of arrival matter
