## Overview

This is a personal competitive-programming code library: users browse topic-organized algorithm and data-structure templates, study or adapt a relevant template, and apply it in their own solutions. The README also points users to an external topic list for related problems, tutorials, and progress tracking. Source excerpts show standalone examples rather than a shared runtime or internal call pipeline, so the graph models the documented discovery workflow and major topic areas, not unsupported dependencies between snippets.

Main entry points: [`Basics`](https://github.com/shahjalalshohag/code-library/tree/main/Basics) (Basic Techniques), [`Miscellaneous`](https://github.com/shahjalalshohag/code-library/tree/main/Miscellaneous) (Miscellaneous), [`Data Structures`](https://github.com/shahjalalshohag/code-library/tree/main/Data%20Structures) (Data Structures), [`Dynamic Programming Optimizations`](https://github.com/shahjalalshohag/code-library/tree/main/Dynamic%20Programming%20Optimizations) (DP Optimizations)
