The free companion source code repository for the Competitive Programming 4 book, containing implementations of well-known data structures and algorithms in C++17, Java 11, Python 3, and OCaml. It serves as a reference library that programmers can copy, adapt, and use in contests or other coding projects.

Use cases

• study data structures and algorithms for competitive programming
• find reference implementations of classic algorithms before a contest
• copy well-tested algorithm templates like segment trees or graph algorithms
• compare algorithm implementations across C++, Java, Python, and OCaml
• supplement reading the Competitive Programming 4 book with runnable code
• prepare for ICPC or Codeforces contests with reusable code snippets

When to choose

• you are preparing for programming contests and want battle-tested algorithm templates
• you want to learn how classic data structures and algorithms are implemented in multiple languages
• you are reading the CP4 book and want its accompanying code
• you need a quick reference implementation rather than writing algorithms from scratch

When to avoid

• you need a production-ready algorithm library with package management and versioned releases
• you want a general-purpose data structures library to use as a dependency in applications
• you need code with a formal open-source license file for commercial redistribution
• you are looking for tutorials or explanations rather than source code
