## Overview

This repository is a collection of independent Java solutions to algorithm and programming exercises, not a single application. The workflow is a caller supplying inputs to one solution method and receiving its result; there is no shared runtime orchestrator or storage layer. The graph groups representative solutions by problem domain. The README provides no further product details, and sampled source confirms several standalone methods; other listed solutions are represented by their paths and names, not inspected implementations.
