Programming
Difficulty: Hard
Arrays And Strings
Prepare more deliberately for Programming revision with Arrays And Strings (hard). This 26-question interview-focused practice test turns the topic into a structured practice session. The attempt uses a 30-minute timer and hard difficulty so you can practise with clear conditions.

🎯 Coverage: The questions cover arrays, strings, and hash maps; time and space complexity; binary search and sorted-space reasoning; caching and hot-key protection; linked lists, stacks, and queues; and trees, graphs, and traversals. Use the scenarios to practise separating a plausible shortcut from an approach that remains maintainable at production scale.

Treat incorrect answers as design-review notes: identify the overlooked constraint and practise defending a safer alternative.
