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 ...

the distribution may be sufficiently balanced such that there may be un-occupied slots for a given hash value. That is, as long as the entire hash table is not full, one of the 64 potential slots for the hash table index is likely to be unoccupied so that the hash table index can be...
