## Overview

This is an archive of independent C++ competitive-programming exercises and problem solutions, not a single application. The usual workflow is to choose a problem file, provide its input when run as a standalone program, and read its computed output. The graph highlights the current PACODE beginner focus, other PACODE practice, earlier basic-C++ study, and separate Luogu practice. README-described topics and collections are preserved; sampled files show independent programs, not shared runtime wiring.
