1. 原题链接 https://leetcode.com/problems/search-in-rotated-sorted-array/description/ 2. 题目要求 给定一个按升序排列的数组nums[ ]和目标值target,将数组在某点处进行旋转,然后在旋转后的数组中查找与target相同的元素,存在返回其下标,不存在返回“-1”. 注意:旋转点未知! 例,{1, 2, 3, 4, 5, 6, 7}旋转后可能为: {4, 5, 6, 7,1,2, 3} {3, 4, 5, 6,…

题目: Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1.…

题目描述:在一个旋转数组中查找给定的值,其中旋转数组中不含重复值: 思路: 第一遍二分遍历,找到数组中最小值的索引: 第二遍分别对最小值左右两边的数组进行二分查找: class Solution(object): def find_min(self, nums): if not nums: return -1 left, right = 0, len(nums) - 1 while nums[left] > nums[right]: if right - left == 1: return ri…

描述 Follow up for ”Search in Rotated Sorted Array”: What if duplicates are allowed?    Would this affect the run-time complexity? How and why?    Write a function to determine if a given target is in the array. 如果循环数组里有重复元素,则根据A[m]>=A[l]是无法判断出(m,l)之间是…
