Add solution for max subarray with character input

[greypz]

Hi i added the sollution and used kadane's algorithm however in kadane's algorithm negative values are also acceptable.
wouldn't a simpler sum algorithm be better for this kind of problem?

What’s Good

• User Input Loop implemented correctly with exit condition (x).
• Kadane’s Algorithm is used properly to compute maximum subarray sum.
• Handles empty input gracefully.
• Outputs result in the correct format: Maximum subarray sum = X.

Minor Issues

• Input Type Not as Per Prompt
  Prompt expects input as non-negative integer characters, e.g. ['1', '2', '3'], but current implementation directly accepts integers including negatives like -2, -1.

  📌 Solution: Accept inputs as string characters, validate they are digits, then convert to integers.

• No Explicit Character to Integer Conversion Step
  As per the requirement, character list should be explicitly converted to integers using list(map(int, char_list)).

  📌 Currently, input is already integer — so this step is implicitly skipped.

---

Your solution is almost complete and works great logically — just a small adjustment to input format will make it fully aligned with the problem statement. Great job overall! 👍

Thanks a lot for detailed feedback, i've adjusted the code acording to your feedback
