Given a binary tree with the following rules: root.val == 0 If treeNode.val == x and treeNode.left != null, then treeNode.left.val == 2 * x + 1 If treeNode.val == x and treeNode.right != null, then treeNode.right.val == 2 * x + 2 Now the binary tree is contaminated...
Write a Python program to find the kth smallest element in a given binary search tree.Sample Solution: Python Code:class TreeNode(object): def __init__(self, x): self.val = x self.left = None self.right = None def kth_smallest(root, k): stack = [] while root or...
Given a binary search tree (BST) with duplicates, find all themode(s)(the most frequently occurred element) in the given BST. 给定具有重复项的二叉搜索树(BST),找到给定BST中的所有众数(最频繁出现的元素)。 Assume a BST is defined as follows: 假设BST定义如下: The left subtree of a node con...

501. Find Mode in Binary Search Tree Given a binary search tree (BST) with duplicates, find all the mode(s) (the most frequently occurred element) in the given BST. Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less than or equal to ...
Given a binary search tree (BST) with duplicates, find all the mode(s) (the most frequently occurred element) in the given BST. Assume a BST is defined as follows:* The left subtree of a node contains only nodes with keys less than or equal to the node's key. ...
Another solution to the problem is by traversing the tree from bottom and checking if it is BST using its child nodes. For this the node, we will keep track for If it is a BST or not. The value of maximum element, in case of left subTree. Minimum element, in case of right su...

Firstly, we will have an array B, B[i] = 1 if ith element not deleted yet, B[i] = 0 otherwise. We will build a Segment Tree whose each node has 1 value, it is the sum B[i] in [L, R]. Now, we can find the kth element in the array easily by binary search. Code: ...
