    def max_subarray_sum(arr):
    max_sum = float('-inf')
    current_sum = 0
    for num in arr:
        current_sum = max(num, current_sum + num)
        max_sum = max(max_sum, current_sum)
    return max_sum

  5. Code Analysis: The AI analyzes your code, checking for correctness and efficiency.

  6. Follow-up Questions: The AI asks follow-up questions, such as:

    • What is the time and space complexity of your solution?
    • How would you modify the algorithm to return the start and end indices of the maximum subarray?

  7. Performance Feedback: At the end of the session, the AI provides detailed feedback on your problem-solving approach, communication skills, and coding style.
