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 ...
1、 严格单调递增 2、 有一个拐点 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...
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...
classSolution {public:intfindMin(vector<int> &num) {intsize = num.size() -1;intl =0;intr =size;while(l <r) {intmid = (r + l) /2;if(num[mid] >num[r]) { l= mid +1; }else{ r=mid; } }returnnum[l]; } };
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...
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] )。
Find Minimum in Rotated Sorted Array I 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. ...
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
This is a follow up problem to Find Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why? 1. 2. 题目大意: 求出经过旋转的有序数组的最小值(数组中含有重复元素) 解题思路 —— 折半查找
