In this post , we will see how to convert sorted LinkedList to balanced binary search tree. There are two ways to do it. Solution 1: It is very much similar to convert sorted array to BST. Find middle element of linked list and make it root and do it recursively. Time complexity : ...
Given an array 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 of the two subtrees ofeverynode never differ by more than 1. Example: Given the sorted array:...
Convert Sorted Array to Binary Search Tree Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 解题思路: 题意为构建有序数组的二分查找树。 比較简单。用递归方法就可以,中间的元素作为根节点,前半部分作为左孩子树,右半部分作为右孩子树。
Given an integer arraynumswhere the elements are sorted inascending order, convertit to aheight-balancedbinary search tree. Example 1: Input:nums = [-10,-3,0,5,9]Output:[0,-3,9,-10,null,5]Explanation:[0,-10,5,null,-3,null,9] is also accepted: ...
总结: sorted array -> balanced bst ** Anyway, Good luck, Richardo! My code: /** * Definition for a binary tree node. * public class TreeNode { * int val; * TreeNode left; * TreeNode right; * TreeNode(int x) { val = x; } ...
Let the function to build the balanced BST from the sorted array is:buildBST() which has parameters: sorted array, lower index, higher indexhas return type: TreeNode* // returns the root actuallyFunction buildBST(sorted array, lower index , higher index) 1. Base case: IF lower index>...
Given an array 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 of the two subtrees of every node never differ by more than 1. ...
Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 题意: 将一个有序的数组转化为二叉查找树 解题思路: 这题和上一题convert-sorted-list-to-binary-search-tree这题差不多 还是找出数组中点,以该中点为根 然后依次递归构造左右子树就行 这里需要注意的是...
