LeetCode ProblemMinimize the Maximum Adjacent Element Difference
You are given an array of integers nums. Some values in nums are missing and are denoted by -1. You must choose a pair of positive integers (x, y) exactly once and replace each missing element with either x or y. You need to minimize the maximum absolute difference between adjacent elements of nums after replacements. Return the minimum possible difference.
