Can you solve this real interview question? Convert Sorted Array to Binary Search Tree - Given an integer array nums where the elements are sorted in ascending order, convert it to a height-balanced binary search tree. Example 1: [https://assets.lee
TreeNode*root =newTreeNode(arr[(start + end)/2]); root-> left = sortedArrayTree(arr, start, (start + end)/2-1); root-> right = sortedArrayTree(arr, (start + end)/2+1, end);returnroot; }//给定有序链表,构造高度平衡二叉树TreeNode *sortedListToBST(ListNode *head) {if(!head)...

Given a normal binary tree, convert it into a Left–child right–sibling (LC–RS) binary tree. Each node in the LC–RS binary tree has two pointers: one to the node's left child and one to its next sibling in the original binary tree.

For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1.Example:1.一看之下感觉和108很像，后来发现是linklist，就又不会做了=。=于是在youtube上找到了公瑾讲解 2.这道题...
