Shortest unsorted subarray

CodingAlgorithms & data structuresMid–Senior~25 min

Given an integer array a, find the length of the shortest contiguous subarray that, if sorted in place, would make the entire array sorted in ascending order. If the array is already sorted, return 0.

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
