📚 USM Competitive Programming Handbook

A comprehensive collection of algorithms and data structures for competitive programming, maintained by Universidad Técnica Federico Santa María (USM) students.

🚀 Quick Start

Prerequisites

• Typst - A modern markup-based typesetting system

Compilation

This generates a PDF handbook with all algorithms organized by category.

📖 Contents

The handbook includes implementations for:

• 🔧 General - Templates and troubleshooting guides
• 🔤 Strings - String processing algorithms (KMP, Z-algorithm, Suffix Array, Trie, etc.)
• ⚡ Algorithms - General algorithms (Mo's algorithm, Tortoise-Hare cycle detection)
• 📊 Data Structures - Advanced data structures (Segment Trees, Fenwick Trees, Treaps, etc.)
• 🧮 Mathematics - Number theory, linear algebra, and polynomial operations
• 📈 Graphs - Graph algorithms (DFS, BFS, Shortest paths, Network flows, etc.)
• 📐 Geometry - Computational geometry (Convex Hull, Point operations, etc.)
• 🎯 Dynamic Programming - DP optimizations and classic problems
• 🔀 Combinatorics - Advanced combinatorial algorithms

📝 Contributing Guidelines

Code Style

• Naming: Use lowercase with hyphens for folders and files (knuth-morris-pratt → kmp)
• File Extensions: Only .cpp and .typ files allowed
• Indentation: Use exactly 2 spaces (no tabs)
• Length: Keep filenames under 18 characters when possible
• Atomicity: Each file should contain only one algorithm/data structure

Code Requirements

• Documentation: Every C++ file must start with a multi-line comment describing the algorithm
• No Macros: Avoid competitive programming macros like rep, repx, etc.
• Clean Code: Write readable, well-structured code
