393. Minimum Absolute Distance Between Mirror Pairs

You are given an integer array nums. A mirror pair is a pair of indices (i, j) such that: - 0 <= i < j < nums.length, and - reverse(nums[i]) == nums[j], where reverse(x) denotes the integer formed by reversing the digits of x. Leading zeros are omitted after reversing, for example reverse(120) = 21. Return the minimum absolute distance between the indices of any mirror pair. The absolute distance between indices i and j is abs(i - j). If no mirror pair exists, return -1.
