ICPC Team Reference Notebook (C++11)

A highly optimized collection of core data structures and classic algorithms optimized for competitive programming contests (ICPC Competitions, Codeforces, TopCoder, etc.). This repository serves as a permanent digital codebook, refined for fast copy-pasting, minimal constant-factor overhead, and strict C++11 standard environments.

⚡ Design Philosophy & Contest Constraints

• C++11 Compliance: Code structures strictly avoid post-C++11 language extensions to ensure seamless compilation on older contest servers (e.g., standard judge environments).
• Stack-Overflow Countermeasures: Massive structures allocation footprints use heap-backed storage models to entirely eliminate stack-exhaustion errors under deep recursion or massive limits.
• Amortized Execution Profiles: Algorithmic implementations focus heavily on optimizing tight loops to maximize execution speed against strict time limits.
