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 problem that you would like me to work upon. Note that it may take a few days to answer it.
Dedicated to 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 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
