LeetCode 3761 Explained: Mirror Pairs Solution with Python
In this problem, a mirror pair is a pair of indices (i, j) such that i < j and reverse(nums[i]) == nums[j]. Reversing drops leading zeros, so reverse(120) = 21. The goal is to return the minimum index distance among all such pairs, or -1 if none exist. The constraints are large enough—up to 10^5 … Read more
