Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. 示例1: 输入:root = [3,9,20,null,null,15,7] ...
The routines are generic so even though the structure of any one specific tree is fixed, an application can include several trees that have different structures with no additional code requirements. An example that illustrates how the application can be integrated into an existing code is included....
A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a few nodes. ...
