| 💡 Smart Description | The code snippet defines a binary tree node with methods to calculate the maximum ancestor difference between two nodes. The maxAncestorDiff method calculates the minimum and maximum value of each child, based on their values in its parent's children by comparing them into This code snippet defines a class Solution with a method maxAncestorDiff that calculates the maximum difference between any node value and its ancestor value in a binary tree. It uses a helper method to recursively traverse the tree and update the minimum and maximum values encountered |
