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 discrepancy, 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.
