Can you solve this real interview question? Binary Search - Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -
Input:root = [4,2,7,1,3], val = 5Output:[] Constraints: The number of nodes in the tree is in the range[1, 5000]. 1 <= Node.val <= 107 rootis a binary search tree. 1 <= val <= 107 FindTabBarSize FindBorderBarSize
This is an extremely important question, if you are going for an interview. I repeat:this is an extremely important question, if you are going for an interview. If you do not remember it by heart, I will repeat again. The solution of the iterator applies to a lot of related questions....

It's also a leetcode problem.The in-order traversal gives you an ordering of the elements. You can reconstruct the original binary tree by adding elements to a binary search tree in the pre-order traversal order, with "<=>" determined by the in-order traversal, instead of using <, >,...
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: ...
Both the left and right subtrees must also be binary search trees. Example 1: Input:root = [1,null,2,2]Output:[2] Example 2: Input:root = [0]Output:[0] Constraints: The number of nodes in the tree is in the range[1, 104]. ...
