Leetcode Find Minimum in Rotated Sorted Array 题目大意: 对一个有序数组翻转, 就是随机取前K个数,移动到数组的后面,然后让你找出最小的那个数。注意,K有可能是0,也就是没有翻转。 毫无疑问,遍历一次肯定能够找到,但这样时间复杂度是O(n)。假设你在面试的时候遇到这种问题,你这样回答面试官肯定不会惬意的。
1. 无重复 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. 思路:这个是找最小,和找指定数字其实差不多的。画个示意图吧 二分...
LeetCode 153. Find Minimum in Rotated Sorted Array 程序员木子 香港浸会大学 数据分析与人工智能硕士在读 来自专栏 · LeetCode Description 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...
Find the minimum element. You may assume no duplicate exists in the array. 思路分析:这题主要考察二分查找,在Rotated Sorted Array中找最小和Search in Rotated Sorted Array相似,仅仅只是此时须要不断把最左边的元素A[l]与A[m]比較 1. 假设A[m] < A[l] 那么应该在左边找,更新右边的边界right。 2...

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] )。
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
Given the sorted rotated array nums of unique elements, return the minimum element of this array. You must write an algorithm that runs in O(log n) time. <a href="https://leetcode.com/problems/find-minimum-in-rotated-sorted-array/description/" target="_blank">Leetcode Link</a> ...
Follow up for "Find Minimum in Rotated Sorted Array": What if duplicates are allowed? Would this affect the run-time complexity? How and why? Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. ...
问题描述: Suppose an array sorted in ascending(升序) order is rotated at some pivot(枢轴; 中心点) unknown to you beforehand(提前,事先). (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You... 查看原文 LeetCode154.寻找旋转排序数组中的最小值 ...
