RecursionError: maximum recursion depth exceeded in compari…

A function is likely calling itself recursively without a proper stopping condition, leading to an infinite loop of function calls. This eventually exceeds Python's maximum recursion depth limit.

The root cause is that the recursive function does not have a base case that terminates the recursion, or the base case is never reached due to incorrect logic.

To fix this, ensure that the recursive function has a clear base case that will eventually be met. Review the logic to confirm that the function will progress towards this base case with each call.
