ps is a collection of various computing problems and their corresponding solutions
that I could think of. The problems range in various categories such as design,
algorithms, performance optimizations, and more.
Feel free to add a Github issue for any discrepency, typo, alternatives, or a different solution that I might not have considered. Also feel free to add issues for problems that you would like me to work upon - though it may take me a few days to research and jot my notes here.
If you wish to contribute please read the guidelines.
Dedicated to all the friends who inspired me to learn and experiment.
The following is a list of the various problems and their solutions:
- Discussion on how finding duplicates in integer arrays leads to Bloom Filters
- How to find the top-k IPs hitting a service
- Fastest sorting of bounded integers
- Fastest way to merge multiple integer sets
- Fastest way to find duplicates in multiple integer sets
- Find degrees of separation in a social graph
- Design a stateless user-session mechanism
- Design a scalable user authentication system
- Design a rate-limited web-scraper
- Design a shopping cart
- Design a notification System
- Design a CRON scheduler
- Design an object-pool or a connection-pool
- Design an email-delivery system like Mailchimp
- Testing for concurrency in Java
- Stop multiple form submission in web requests - also called Replay Attack
