This repository contains my (ongoing) journey of Competitive Coding. It starts from when I stopped using Turbo C++ and tried to wrap my head around Binary Search. This has probably been the most active repository throughout my engineering journey.
For the same reason people write a diary/blog. It's like maintaining a photo album. You don't know if you'll ever need it, but it's nice to keep memories.
