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

Problem Summary You are given: You need to find the shortest distance from startIndex to any index where words[i] == target. Because the array is circular, you can move: If the target does not exist, return -1. Key Observation For every index i where words[i] == target, the circular distance from startIndex is: So the … Read more

Problem Statement You are given an integer array nums. A triple of indices (i, j, k) is called good if: The distance of a good triple is:∣i−j∣+∣j−k∣+∣k−i∣|i-j| + |j-k| + |k-i|∣i−j∣+∣j−k∣+∣k−i∣ Your task is to return the minimum possible distance among all good triples. If no value appears at least 3 times, return -1. Example … Read more
