Suggested Approach

First, clarify the encoding scheme and constraints by asking questions and walking through examples. Then, design an algorithm that decodes the numbers efficiently, discussing trade-offs between approaches. Finally, implement and test the solution, ensuring edge cases are handled.

Pro tip: Demonstrate strong communication by thinking aloud and explaining your reasoning at each step, as Point72 values collaborative problem-solving. Also, relate the problem to real-world applications in finance, such as decoding market data or encrypted messages.

1. Understand the Problem

Ask clarifying questions to fully understand the encoding scheme, input format, and expected output. Confirm constraints and edge cases with the interviewer.

2. Explore Examples

Work through small examples manually to identify patterns and validate your understanding. Discuss potential edge cases and how they might affect the solution.

3. Design an Algorithm

Propose a high-level approach, considering time and space complexity. Discuss alternative solutions and justify your choice based on efficiency and clarity.

4. Implement the Solution

Write clean, modular code with meaningful variable names. Explain your code as you write and handle edge cases gracefully.

5. Test and Optimize

Walk through test cases, including edge cases, to verify correctness. If time permits, discuss potential optimizations or alternative implementations.

Key Points to Mention

  • Clarify the encoding scheme and constraints before coding.
  • Consider multiple approaches and analyze time/space complexity.
  • Handle edge cases such as empty input, invalid encoding, or overflow.
  • Write clean, readable code with comments and meaningful names.
  • Test with a variety of cases, including edge cases.
  • Communicate your thought process clearly throughout.
