Descriptive code and explanation of popular data structure and algorithm problems in C++
- Crisp and clean implementation of classic algorithm problems
- Consistent code convention across all the problems
- Keep it simple! Learn and grow together.
- The repository is organized as Topic - Subtopic - Problem_ShortName.
- Each Problem_ShortName folder is expected to contain following files
- One solution file
- One Problem_ShortName.in file (input for algorithm demo)
- One Problem_ShortName.out file (output for algorithm demo)
- One Problem_ShortName.md file per algorithm with easy to understand explanation of solution.
- Make sure the markdown file explains the input and output file as well and lists the command to compile and run the example.
