给定一个整数数组,你需要寻找一个连续的子数组,如果对这个子数组进行升序排序,那么整个数组都会变为升序排序. 你找到的子数组应是最短的,请输出它的长度. 示例 1: 输入: [2, 6, 4, 8, 10, 9, 15] 输出: 5 解释: 你只需要对 [6, 4, 8, 10, 9] 进行升序排序,那么整个表都会变为升序排序. 说明 : 输入的数组长度范围在 [1, 10,000]. 输入的数组可能包含重复元素 ,所以升序的意思是<=. class Solution { public: int…

581. 最短无序连续子数组 581. Shortest Unsorted Continuous Subarray 题目描述 给定一个整型数组,你需要寻找一个连续的子数组,如果对这个子数组进行升序排序,那么整个数组都会变为升序排序. 你找到的子数组应是最短的,请输出它的长度. LeetCode581. Shortest Unsorted Continuous Subarray 示例 1: 输入: [2, 6, 4, 8, 10, 9, 15] 输出: 5 解释: 你只需要对 [6, 4, 8,…

problem 581. Shortest Unsorted Continuous Subarray 题意:感觉题意理解的不是非常明白. solution1: 使用一个辅助数组,新建一个跟原数组一模一样的数组,然后排序.从数组起始位置开始,两个数组相互比较,当对应位置数字不同的时候停止,同理再从末尾开始,对应位置上比较,也是遇到不同的数字时停止,这样中间一段就是最短无序连续子数组. class Solution { public: int findUnsortedSubarray(vector<…
