Complexity: Recursive vs Iterative | Dataford Interview Questions

Explain the time and space complexity of your recursive versus iterative solutions.

Implement maximum depth for a binary tree represented as [value, left, right], where an empty subtree is null. Return the tree's maximum number of nodes from the root to any leaf. Discuss the complexity of both recursive and iterative approaches.

Constraints

The tree is null or a valid nested [value, left, right] structure.
0 <= number of nodes <= 1000
Node values are integers.
The tree may be balanced or highly skewed.

Function Signature

def max_depth(tree):
