Input:nums = [2,5,6,0,0,1,2], target = 3Output:false Constraints: 1 <= nums.length <= 5000 -104<= nums[i] <= 104 numsis guaranteed to be rotated at some pivot. -104<= target <= 104 Follow up:This problem is similar toSearch in Rotated Sorted Array, butnumsmay containdup...
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[mid] > nums[right],说明[elft, mid]区间是在左边的递增区间,然后判断target是否在这个左边区间里 1)如果nums[left] <= target < nums[mid],说...
初始版本 题目描述 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. You ma...
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?
publicintsearch(int[]nums,inttarget){intlo=0,hi=nums.length-1;while(lo<=hi){intmid=lo+(hi-lo)/2;intnum=nums[mid];//nums [ mid ] 和 target 在同一段if((nums[mid]<nums[0])==(target<nums[0])){num=nums[mid];//nums [ mid ] 和 target 不在同一段,同时还要考虑下变成 -inf 还...

https://leetcode.com/problems/search-in-rotated-sorted-array-ii/ 解题思路 先找到数组被rotated的位置如果有的话。 确定好位置之后再在排序的数据区间内查找元素。 代码 class Solution{public:boolsearch(vector<int>&nums,inttarget){if(nums.empty()){returnfalse;}//先查找被反转的位置intpos=findPos(...
