## Overview

This is a small C# console exercise collection, not a multi-tier application: the README describes 20 function and structured-programming exercises selected from a console menu. The sampled code places exercise handlers and their algorithm helpers together in one source file. The excerpt does not show the active menu/dispatch implementation, so the documented selection flow is represented without asserting a specific internal routing mechanism; unsampled exercise internals are left unconnected.
