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. The array may contain duplicates. 解法1:本题旋转数组最小
intfindMinVal(intmin,intmax,constvector<int> &rotateArray) {//取三个点的值intminVal = rotateArray[min];//最左边的点的值intmaxVal = rotateArray[max];//最右边的点的值intmidVal = rotateArray[(min + max) /2];//中间的点的值//终止条件if((max - min) <=1)returnminVal > maxVal ?max...
Find the minimum element. The array may contain duplicates. Example 1: Input: [1,3,5] Output: 1 Example 2: Input: [2,2,2,0,1] Output: 0 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?
154. Find Minimum in Rotated Sorted Array II 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. The array may contain duplicates. Example 1: Input: [...
LeetCode: 154. Find Minimum in Rotated Sorted Array II 题目描述 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]). ...
mid > start : 最小值在左半部分。 mid < start: 最小值在左半部分。 无论大于还是小于,最小值都在左半部分,所以 mid 和start 比较是不可取的。 mid 和end 比较 mid < end:最小值在左半部分。 mid > end:最小值在右半部分。 所以我们只需要把 mid 和end 比较,mid < end 丢弃右半部分(更新 en...
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
Notice thatrotatingan 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 that may containduplicates, returnthe minimum element of this array. ...
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. The array may contain duplicates. 思路: 寻找有序重复数组的最小值是对上一道题目的延伸,当数组中存在大量重...
Find Minimum in Rotated Sorted Array II 理论上这题应该也用二分法,碰到起点终点相同的情况就只能进行遍历,但是那样代码会更复杂并且效率上并不见得提高多少,所以这里我直接采用遍历的方法。 实现代码: javapublic class Solution { public int findMin(int[] num) { ...
