LeetCode 581 Shortest Unsorted Continuous Subarray (Python)

Posted by 小明MaxMing on February 25, 2021

题目

Given an integer array nums, you need to find one continuous subarray that if you only sort this subarray in ascending order, then the whole array will be sorted in ascending order.

Return the shortest such subarray and output its length.

解题思路

用排好序的数组与原数组进行比较,找到第一个与最后一个不相同的位置,这两个位置直接需要排序

代码

class Solution:
    def findUnsortedSubarray(self, nums: List[int]) -> int:
        order = [x == y for x, y in zip(nums, sorted(nums))]
        return 0 if all(order) else (len(nums)) - order.index(False) - order[::-1].index(False)
