Coding Problems
Coding Problems provides solutions to coding and algorithm problems and multiple programming exercises.
About Coding Problems
Coding Problems is a repository of solutions for coding and algorithmic problems with resources for learning algorithms and data structures. All solutions are written in Python 3 using built-in functions and standard library modules such as math, collections, heapq and random, so no external packages are required.
Solutions are organized into categories including Arrays, Linked Lists, Trees, Hashing DS, Dynamic Programming, Strings and Math. Each solution file includes a problem description, solution explanations with time and space complexity, and print-based tests. The repository states it is for learning and research only and not for production.
Key features
- Python 3 solutions using only standard library modules
- Each solution file lists time and space complexity
- Solutions grouped by topic such as Arrays and Trees
- Inline example tests that print expected results
- Learning resources for algorithms and data structures
- Solutions cover Dynamic Programming, Strings, Math and Hashing
Best for: Learners researching algorithms and data structures who can read Python 3.
Good for
- Runs without external packages, using only Python standard library
- Each solution documents time complexity and space complexity
- Code follows PEP8 and stays close to readable pseudocode
Watch out for
- Stated for learning and research only, not for production use
- Testing relies on print statements rather than a test framework
