These are all the submissions I have made on Leetcode compiled into a Github repository for all to see. I am currently going through the Leetcode problems in the Neetcode Roadmap.
Some of these solutions are ones that I came up with, while others are inspired by or entirely the same as solutions from Neetcode's materials. I try the problem myself for 45 to 60 minutes and if I cannot come up with anything, I watch the videos.
