The problem reference in the source was encoded in a way I couldn't fully decode, so I can't tell you exactly which one it was.
Start by clarifying the problem constraints and edge cases, then discuss a brute-force solution before optimizing with appropriate data structures or algorithms. Walk through your thought process, analyze time and space complexity, and test your solution with examples.
Pro tip: At Apple, they value clean, efficient code and attention to detail. Always consider edge cases and discuss trade-offs between different approaches, showing you can think like a production engineer.
Ask clarifying questions to confirm input/output formats, constraints, and edge cases. Restate the problem in your own words to ensure alignment.
Discuss a brute-force solution first, then propose optimizations using suitable data structures or algorithms. Explain the trade-offs.
Write clean, modular code with meaningful variable names. Verbally explain each step as you code to demonstrate your thought process.
Walk through test cases, including edge cases, to verify correctness. If issues arise, debug systematically and explain your reasoning.
State the time and space complexity of your solution and discuss potential improvements or alternative approaches.
