There are several types of folder.
- First type is the online judges folder prefixed by OJ_ . These are the online judges I've used to practice my problem solving.
- Second type is the folders I've used for my own practice and bug fixes, these are the Tests, Tricks, Learn folders
- Third type is the outside code folders, these are the folders that have mostly codes that I didn't write. Like: External, Programming Contest Book, Remember_solution etc
- The next type is the contest, seasons types, These are the periodic solutions that I needed to do from time to time.
