Lowest common ancestor of a binary tree iii pythonBroadly speaking, nodes with children are harder to delete. As with all binary trees, a node's inorder successor is its right subtree's leftmost child, and a node's inorder predecessor is the left subtree's rightmost child. In either case, this node will have zero or one child. Delete it according to one of the two simpler cases above.The lowest common ancestor in the binary tree for nodes 6 and 3 is 4. Note: To find common ancestors, you don't need to sort the nodes in a Binary tree. This solution works even if the nodes are in an unsorted order. Complexity. To calculate the ancestors of any node in the binary tree takes the time of O(n).【问题标题】:二叉树中的最低共同祖先(Lowest Common Ancestor in a Binary tree) 【发布时间】:2012-11-08 18:34:23 【问题描述】: 以下是我对二叉搜索树的最低共同祖先的实现。Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree.
