Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 二、分析 这题难度有,因为他默认的是数组中所有的元素是不同的。只有分为两种情况...
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
所以就随便搜了下Garnker的,知道是Search in Rotated Sorted Array,那题是找目标值。这里是找最小值。 我是这样想的,分为几部分, 1.如果左边的值等于中间的值了,那么就剩下两个数要判断了,而且是相邻的。 2.如果中间的值大于左边的值,那么最小值肯定不是在最左边就只在右边一块了。 3.如果中间值小于左...
而Find Minimum in Rotated Sorted Array II这道题这考虑了元素反复的情况,这里仅仅是为了算法更加一般性。就把那个情况也包括进来,有兴趣的朋友能够看看Find Minimum in Rotated Sorted Array II对反复元素的分析哈。
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...
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] )。
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.
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. ...
上一题是没有重复的数字,这一题有重复数字,完全和offer上一样。代码如下: classSolution(object):deffindMin(self,nums):""" :type nums: List[int] :rtype: int """iflen(nums)==0:return-1iflen(nums)==1:nums[0]left=0right=len(nums)-1printleftprintrightifnums[left]<nums[right]:returnnum...
Java program to find minimum element in a sorted and rotated array : If you want to practice data structure and algorithm programs, you can go through data structure and algorithm interview questions. In this post, we will see how to find minimum element in sorted and rotated array. Problem...
