python
Visa detaljer RecursionErrorThe maximum recursion depth was exceeded.
A function called itself (directly or indirectly) too many times without reaching a base case. Python's default recursion limit is 1000. Infinite recursion, deeply nested data structures, or algorithms with excessive recursion depth trigger this.
Add or fix the base case in your recursive function. Convert deep recursion to iteration using a stack. Increase the limit with sys.setrecursionlimit() (use cautiously as it can crash Python). Use functools.lru_cache for memoization.
