LeetCode Top 100 Liked Questions 105. Construct Binary Tree from Preorder and Inorder Traversal (Java版; Medium) 题目描述 Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. For example, given preorder ...
Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants (where we allow...
https://leetcode.cn/problems/number-of-ways-to-reconstruct-a-tree 这道题曾经在周赛难度分top1呆了几年,如今已经不在难度分top5了。破局的关键是父节点的邻居数肯定不少于子节点,而根节点的邻居数一定是n-1。所以应该先找到根节点,然后逐层向下建树,子节点的邻居一定是父节点的子集,否则就是非法;如果子...
