01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第25题(顺位题号是108)。给定一个数组,其中元素按升序排序,将其转换为高度平衡的二叉搜索树。例如: 给定排序数组:[ -10,-3, 0, 5, 9] 一个可能的答案是:[0,-3, 9,-10,null,5],它代表以下高度平衡的二叉搜索树: 0 / \ -3 9 / / -10 ...
The method described in the theory performs binary search for arrays sorted in ascending order. Your task here is to modify the method such that: it allows searching in descending sorted arrays; it returns the first index of a target element from the beginning of the array (the leftmost index...

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。 /** * Defini...
