RecursionError: maximum recursion depth exceeded in comparison

This error occurs when a program or function calls itself too many times, causing the computer to run out of memory for the recursive calls.
To fix this error, you can try the following:
1. Increase the recursion limit: You can increase the maximum recursion depth using the sys.setrecursionlimit() function. However, increasing the recursion limit may not always be the best solution as it can lead to other errors such as stack overflow.
2. Optimize the code: Analyze your code and see if there are any unnecessary recursive calls that can be eliminated. You may be able to restructure your code to use iteration instead of recursion.
3. Use tail recursion: Tail recursion is a technique where the recursive function call is the last operation in the function. This allows the compiler to optimize the code and reduce the memory usage.
4. Use memoization: Memoization is a technique that involves caching the results of function calls to avoid making the same computation multiple times. This can help reduce the number of recursive calls and improve performance.
5. Use a different algorithm: In some cases, a different algorithm may be more efficient and require fewer recursive calls. Analyze your problem and see if a different approach can be used.
