maximum recursion depth exceeded

This error message is encountered when a Python program exceeds the maximum recursion depth limit. Recursion is a technique in which a function calls itself repeatedly until a certain condition is met. However, if the recursion depth is too high, it can lead to a stack overflow error and cause the program to crash.

To fix this error, you can increase the recursion limit using the sys module:

import sys
sys.setrecursionlimit(10000) # set the recursion limit to 10,000

Alternatively, you can refactor the code to use an iterative approach instead of recursion. This can be done by using loops or using a stack or queue to keep track of function calls instead of relying on the call stack.
