## What it is
A curated collection of 180+ algorithm and data structure problems solved in C++ (with a small number of Python solutions), covering topics like linked lists, trees, bit manipulation, and string manipulation. It is intended as interview practice material, organized by problem category with one solution file per problem.

## Use cases
- prepare for coding interviews with practice problems
- learn data structures and algorithms in C++
- study linked list and tree problem solutions
- practice leetcode-style problems offline
- review classic algorithm questions before an interview
- learn bit manipulation and string manipulation techniques

## When to choose
- you are preparing for technical interviews and want worked C++ solutions
- you want a categorized reference of classic algorithm and data structure problems
- you are learning C++ and want to see many small, focused example programs

## When to avoid
- you need production-quality, safe, or well-tested code - the author warns some code is old and may be unsafe
- you want a runnable test suite or package rather than standalone solution files
- you need Python-first coverage - only ~15 of the problems have Python solutions

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, programming-languages
- platform: cpp, python, cross-platform
- tags: interview-preparation, data-structures, leetcode, coding-interview, practice-problems, bit-manipulation, trees, linked-lists, algorithms
