but given a node, how to check if it is or not, we should do this: isBalanced(root) = Math.abs(height(root.left) - height(root.right)) < 1 classSolution{publicbooleanisBalanced(TreeNode root){if(root ==null)ret
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...
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 ...

Given a binary tree, check if removing an edge can split it into two binary trees of equal size. For example, removing the edge1 —> 2from a binary tree on the left below splits it into two binary trees of size 3. However, there is no edge whose removal splits the binary tree on...
