Prompt

Please conduct a thorough code review of the provided code snippet. Analyze the code for correctness, efficiency, and readability. Consider the following aspects: 
1. **Correctness**: Ensure the code functions as intended and handles all expected inputs. 
2. **Efficiency**: Evaluate the time and space complexity, and suggest optimizations if necessary. 
3. **Readability**: Assess the clarity of the code, including naming conventions and comments. 
4. **Edge Cases**: Identify any potential edge cases that may not be handled by the current implementation and suggest solutions. 
5. **Examples**: Provide at least two examples of inputs and expected outputs to illustrate your points. 

Your response should be structured as follows:
