力扣leetcode-cn.com/problems/binary-search/ 题目描述 给定一个 n 个元素有序的(升序)整型数组 nums 和一个目标值 target ,写一个函数搜索 nums 中的 target,如果目标值存在返回下标,否则返回 -1。 示例1: 输入: nums = [-1,0,3,5,9,12], target = 9 输出: 4 解释: 9 出现在 nums 中并且...
as we mentioned before, the binary search idea can happens almost anywhere, like implement pow(x, n) function and search rotated array, and many other unexpected, not so explicit senerio. we need to dig deeper to that binary search, and especially, the boundary problems, those are really p...
