题目来源: https://leetcode-cn.com/problems/find-minimum-in-rotated-sorted-array-ii/ 题目描述: 代码如下: leetcode 153[medium]---Find Minimum in Rotated Sorted Array 难度:easy Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., 0 1 ...
我们须要分情况处理。当然也能够无论这些直接遍历,即从头到尾扫描,找出最小的数;假设依据题意,我们须要考虑 1、 当严格单调时,因为是排好序的所以我们直接return 第一个元素就可以;或者直接利用二分法查找也能够。 2、 当有拐点时,我们就能够二分查找高速找到最小值。 综上所诉。考虑两种情况能够提高效率,可是直...
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...
一、题目描述 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...
Suppose a sorted array is rotated at some pivot unknown to you beforehand. 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: 有序数组旋转后,如果mid元素比low大,则左边有序,右边乱序,考虑最左元素是否最小元素...
【摘要】 Leetcode 题目解析之 Find Minimum in Rotated Sorted Array Suppose a sorted array 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.
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,遍历一次肯定可以找到,但这样时间复杂度是O(n),如果你在面试的时候遇到这样的问题,你这样回答面试官肯定不会满意的...
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] )。
The array may contain duplicates. Example 1: Input: [1,3,5] Output: 1 1. 2. Example 2: Input: [2,2,2,0,1] Output: 0 1. 2. Note: This is a follow up problem to Find Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why?
Suppose a sorted array 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. 二分迭代法 复杂度 ...
