1. nums[mid] = target,则可以返回mid 2. nums[mid] < nums[right],说明在[mid, right]区间是右边递增的区间,然后判断target是否在这个区间内 1)如果nums[mid] < target <= nums[right],说明target在右边区间里,则left = mid + 1; 2)否则在左边区间里,搜索左边区间,right = mid - 1; 3. nums[m...

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). Write a function to determine if a given target is in the array. The array may contain duplicates. 这道题很简单,直接遍历即可。...
【Leetcode】Search in Rotated Sorted Array II 题目链接:https://leetcode.com/problems/search-in-rotated-sorted-array-ii/ 题目: Follow up for “Search in Rotated Sorted Array”: What if duplicates are allowed? Would this affect the run-time complexity? How and why?
This is a follow up problem to Find Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why? 描述 假设按照升序排序的数组在预先未知的某个点上进行了旋转。 ( 例如,数组 [0,1,2,4,5,6,7] 可能变为 [4,5,6,7,0,1,2] )。
int bs(int *nums,int numsSize,int target)//bs为二分搜索函数 { int low = 0; int high = numsSize - 1; while(low <= high) { int medium = (low+high )/2; if(nums[medium] == target)return medium; else if(nums[medium] > target)high = medium - 1; else low = medium+1; }...
Can you solve this real interview question? Find Minimum in Rotated Sorted Array - Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become: * [4,5,6,7,0,1,2] if
寻找旋转排序数组中的最小值 II 思路解题方法复杂度 Code 思路该方法采用二分查找的变种,逐步缩小搜索范围,最终找到数组中的最小值解题方法 如果 nums[mid] 等于 nums[right],这意味着 mid 到 right 之间的元素可能存在重复值。通过将 right 二分查找 数组 Python3 1 97 0...
