Balanced binary trees are also known as height-balanced binary trees. Height balanced binary trees can be denoted by HB(k), where k is the difference between heights of left and right subtrees. ‘k’ is known as the balance factor. If for a tree, the balance factor (k) is equal to ...
Implement a function to check if a binary tree is balanced. For the purpose of this question, a balanced tree is defined to be a tree such that the heights of the two subtrees of any node never differ by more than one. 这道题让我们检查一棵树是不是平衡的,根据题目平衡二叉树的定义我们...
