## Description

This project is an algorithm implementation repository and coding interview practice guide. It provides a collection of algorithmic solutions, data structure references, and study materials designed to prepare candidates for software engineering hiring assessments.

The repository functions as an algorithm test suite, utilizing a case-driven verification system that executes specific input-output pairs to validate the correctness of the implemented logic.

The codebase covers technical interview preparation through the practice of common computer science problems, the implementation of core data structures, and the verification of coding solutions.
