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:...
35. Search Insert Position [Easy] Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You may assume no duplicates in the array. Example: Input:[1,3,5,6],5Output:2 Input:[1...

[Leetcode][python]Convert Sorted Array to Binary Search Tree,题目大意将一个排序好的数组转换为一颗二叉查找树,这颗二叉查找树要求是平衡的。解题思路由于要求二叉查找树是平衡的。所以我们可以选在数组的中间那个数当树根root,然后这个数左边的数组为左子树,右边的
Search in sorted arrays¶The most typical problem that leads to the binary search is as follows. You're given a sorted array A0≤A1≤⋯≤An−1 , check if k is present within the sequence. The simplest solution would be to check every element one by one and ...
