## Overview

This repository is a collection of independent C++ contest and practice programs, not a unified application. A typical user runs one executable, supplies problem-specific input, and receives that program’s answer on standard output or a task-specific output file. The graph groups the collection by its directory organization and shows representative standalone workflows; the sampled solutions do not call one another. The tree and excerpts support these examples, but do not establish a shared runtime or how unsampled programs behave.

Main entry points: [`2627 KS3/CAU3.cpp`](https://github.com/aizennguyen/yksw/blob/main/2627%20KS3/CAU3.cpp) (Distinct Window), [`CPPros/GOGOVOI-4.0-NC/Sohoccoban/APP.cpp`](https://github.com/aizennguyen/yksw/blob/main/CPPros/GOGOVOI-4.0-NC/Sohoccoban/APP.cpp) (Next Multiple), [`CoThuy/NguyenGiaBao28-08/matkhau.cpp`](https://github.com/aizennguyen/yksw/blob/main/CoThuy/NguyenGiaBao28-08/matkhau.cpp) (Password Primes), [`Yugihacker/TKNP/A.cpp`](https://github.com/aizennguyen/yksw/blob/main/Yugihacker/TKNP/A.cpp) (Sorted Search)
