The Ultimate Handbook for Data Structures & Algorithms

• src/ – problems, approaches, DS & A to solve
• books/ – to reference specific things
• companies/ – tasks given by a specific firm

Path for studying

1. Take a particular type of problem from src/.
2. Grind all problems from section.
3. Optionally, use books/articles for additional info.
4. Repeat with other types of problems.
