If you discover a security vulnerability in any algorithm implementation, please do not open a public issue.

Instead, please email the maintainer directly or use GitHub's private vulnerability reporting feature if enabled for this repository.

This repository contains educational algorithm template code. Security concerns are primarily about:

• Integer overflow in arithmetic operations (especially under competitive programming constraints)
• Undefined behavior that could affect correctness
• Incorrect bounds leading to out-of-bounds access

• Bounds checking: All array/vector accesses use .at() or explicit range validation
• Overflow awareness: Large-integer operations use long long (ll) and modular arithmetic
• Input validation: Fast I/O patterns include EOF handling
• No external dependencies: All code uses standard library only, minimizing supply chain risk

• No credentials, tokens, or secrets are stored in this repository
• All contributions are reviewed before merge
• Pre-commit hooks enforce code style and catch common issues
