The solution for the problem can be divided into three cases: case 1: if the delete node is leaf node, then we can simply remove it case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid bina…

iven a root of Binary Search Tree with unique value for each node. Remove the node with given value. If there is no such a node with given value in the binary search tree, do nothing. You should keep the tree still a binary search tree after removal.…

从BST中移除一个节点是比较复杂的问题,需要分好几种情况讨论. 如这篇文章,就讨论了删除节点 1.有无左右子树 2.只有右子树 3.只有左子树 三种情况. 一种简单些的思维是只考虑删除节点是否有右子树(因为第一个比删除节点大的节点可能出现在右子树,不会出现在左子树). 这里用Target表示删除节点,Parent表示删除节点的母节点. 1. 没有右子树 Parent.left / Parent.right = Target.left 2. 有右子树 1) 找到第一个比删除节点大的节点Node 2…

题目: Given a root of Binary Search Tree with unique value for each node. Remove the node with given value. If there is no such a node with given value in the binary search tree, do nothing. You should keep the tree still a binary search tree after rem…

For the given tree, in order traverse is: visit left side root visit right side // 6,8,10,11,12,15,16,17,20,25,27 The successor is the one right next to the target: // target 8 --> succossor is 10 So, given the tree and target node, to find its succe…

What is Binary Search Tree (BST) A binary tree in which for each node, value of all the nodes in left subtree is less or equal and value of all the nodes in right subtree is greater The idea: We can use set boundry for each node. We take C tree for e…

Given a binary search tree and a new tree node, insert the node into the tree. You should keep the tree still be a valid binary search tree. Example Given binary search tree as follow: 2 / \ 1 4 / 3 after Insert node 6, the tree should be: 2 / \ 1 4…

1. Convert Sorted List to Binary Search Tree Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth…

Given a binary search tree and a new tree node, insert the node into the tree. You should keep the tree still be a valid binary search tree. Notice You can assume there is no duplicate values in this tree + node.   Example Given binary search tree as…
