This is my personal notes for learning when practicing leetcode problems with the hope of landing a job one day.
I write my mistakes and what I learn for each problem, this is mostly just for myself to review but I decided to share it publicly with my friends.
Hopefully it will be helpful for you at some points.
Pull requests are very welcome. If you have a better answers or spotted some grammar mistakes.
Issues will be mostly for discussion of a particular problem if you have any questions for the answers.
