## Overview

This is a hands-on Java data-structures-and-algorithms practice repository, not an application with a single end-to-end service workflow. The learner’s workflow is to study and implement structures and algorithms across the documented topic areas. The sampled source shows a directly runnable array utility; other branches are included based on the README’s topic map, but their internal wiring is not established by the sampled source.

Main entry points: [`arrays/ArrayUtils.java`](https://github.com/mahnoorahmed-dev/dsa-java/blob/main/arrays/ArrayUtils.java) (Array Utilities)
