In plain English

CP-template is a collection of pre-written C++ code that competitive programmers can copy and reuse during programming contests. Instead of rewriting common algorithms and data structures from scratch every time you compete, you can grab these ready-made templates and focus on solving the actual problem in front of you. The README is sparse on specifics about exactly what algorithms are included, but it does describe one component in detail: a helper for reading input and writing output when working on problems from LeetCode, a popular online judge platform. You set up two text files on your computer, include the project's header file, and register which methods you want to run. The code then handles passing your test cases through your solution automatically. The project follows a set of strict style rules designed to keep the code clean and consistent. Class names use underscores with capital letters, parameters use double underscores, and the code is formatted to a standard style before being finalized. The author welcomes feedback on bugs or design problems. This repository would appeal to someone preparing for programming contests like the ACM International Collegiate Programming Contest, where speed matters and having reliable, tested code snippets ready to go saves precious minutes. It could also help someone practicing algorithmic problems on platforms like LeetCode and wanting a streamlined way to test solutions locally before submitting them online. The README does not list every template included in the repository, so a non-technical reader would need to explore the code files directly to understand the full scope of what's available.
