ACM Cheat Sheet

ACM Cheat Sheet is a compact competitive-programming handbook containing reusable explanations and code for common algorithms and data structures. The same material is maintained in C, C++, and Java editions so readers can study or compete in their preferred language. Topics include fundamentals, linear lists, stacks, queues, strings, trees, graphs, sorting, searching, breadth-first search, and depth-first search. Additional chapters cover greedy methods, divide and conquer, brute force, dynamic programming, mathematics, big integers, and practical programming techniques. The source is written in LaTeX and includes diagrams and downloadable compiled PDF editions. A prepared Visual Studio Code development container supports consistent compilation on Windows, Linux, and macOS. Contributors can extend chapters or correct errors and verify the output locally before submitting changes.
