给定一个特殊升序数组,即一个排序好的数组,把前边的若干的个数,一起移动到末尾,找出最小的数字。 解法一 其实之前已经在 33 题 解法一中写过这个解法了,这里直接贴过来。 求最小值,遍历一遍当然可以,不过这里提到了有序数组,所以我们可以采取二分的方法去找,二分的方法就要保证每次比较后,去掉一半的元素。 这...
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]). Find the minimum element. You may assume no duplicate exists in the array. Example 1: Input:[3,4,5,1,2]Output:1 Example 2...
数组-Find Minimum in Rotated Sorted Array 排序数组在旋转后,可以分为前后两个排序子序列。在没有相同元素的情况下,前一个数组中的元素均大于后一个数组中的元素。 如果我们要找最小元素,则只要找到两个数组的分界点即可,即第二个子序列的开始元素。 由于子序列分别有序,所以我们可以采用二分查找的思想来解决...
153. Find Minimum in Rotated Sorted Array 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]). Find the min element. You may assume no duplicate exists in the array. Example ...
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
Find Minimum in Rotated Sorted Array -- LeetCode 这道题是Search in Rotated Sorted Array的扩展,差别就是如今不是找一个目标值了,而是在bst中找最小的元素。主要思路还是跟Search in Rotated Sorted Array差点儿相同。还是通过左边界和中间的大小关系来得到左边或者右边有序的信息。假设左半边有序。那么左...
Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]]. Given the sorted rotated array nums of unique elements, return the minimum element of this array. ...
153. Find Minimum in Rotated Sorted Array 没有重复的情况。当然要用二分查找,我永远也忘不了头条第一挂,竟然是这么简单的题没整明白。 classSolution(object):deffindMin(self,nums):""" :type nums: List[int] :rtype: int """iflen(nums)==1:returnnums[0]l,r=0,len...
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. Find the minimum element. You may assume no duplicate exists in the array. Problem description: The given problem wants you to use the concept that the array is already sorted but at some point,...
