Xiaomi Software Engineer interview questions

Given an array of integers, write a function to find the indices m and n. As long as the elements in the index range [m, n] are sorted, the entire array will be in order. Note: n-m should be as small as possible, that is, find the shortest sequence that meets the conditions. The function return value is [m,n]. If there is no such m and n (for example, the entire array is ordered), please return [-1,-1].
