Use a fixed-size container with bounds checking
C++: std::array retains its element count and supports checked access through at.
C++✓ Tested
Use a hash map for direct key lookup
C++: unordered_map provides key lookup without promising iteration order.
C++✓ Tested
Use a last-in first-out stack
C#: Stack is useful for reversible traversal and other nested operations.
C#✓ Tested

Use a nonnegative remainder for cyclic indexing
Use a nonnegative remainder for cyclic indexing in a complete Rust program using the standard library.
Rust✓ Tested
Use a switch expression to classify a value
C#: Relational patterns express a small ordered range classification.
