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[mid] > nums[right],说明[elft, mid]区...
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] )。 请找出其中最小的...
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。...
搜索旋转排序数组 Search in Rotated Sorted Array II There is an integer array nums sorted in non-decreasing order (not necessarily with distinct values). Before being passed to your function, nums is rotated at an unknown pivot index k (0 <= k < nums.length) such that the resulting array...
问题出在,当数组剩两个的时候,mid = (start + end)/ 2,mid 取的就是 start。上图的例子, mid > end, 更新 start = mid,start 位置并不会变化。那么下一次 mid 的值也不会变,就死循环了。所以,我们要更新 start = mid + 1,同时也使得 start 指向了最小值。 综上,找最小值的代码就出来了。 pu...
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(...
末尾等于起始,如果未旋转,则全部相等,如果旋转,按 2 处理 关于旋转二分查找是否具有普遍求解。对于一个已经证明是旋转数组的数字。 对于一个旋转数组,如果其前后两个元素相等,说明一定发生了旋转,我们消去这两个元素,其剩下的可能是旋转的,也可能是非旋转的 ...
Search in Rotated Sorted Array Deion: 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...
