## Overview

This repository is a Python data-structures-and-algorithms learning journal, not an integrated application. Its principal workflow is a learner studying a concept, practicing it through implementations, and recording takeaways. The README describes this workflow; sampled files confirm independent examples rather than a shared runtime. Some roadmap topics are documented but have no implementation files in the tree.

Main entry points: [`README.md`](https://github.com/bharath125/data_structure_algorithm/blob/main/README.md) (Learning Journal), [`TimeComplexity/TimeComplexity.md`](https://github.com/bharath125/data_structure_algorithm/blob/main/TimeComplexity/TimeComplexity.md) (Complexity), [`problemConstraints/problemConstratints.md`](https://github.com/bharath125/data_structure_algorithm/blob/main/problemConstraints/problemConstratints.md) (Problem Constraints), [`arrays/concepts`](https://github.com/bharath125/data_structure_algorithm/tree/main/arrays/concepts) (Array Concepts)
