LeetCode ProblemMinimum Operations to Maximize Last Elements in Arrays
You are given two 0-indexed integer arrays, nums1 and nums2, both having length n. You are allowed to perform a series of operations (possibly none). In an operation, you select an index i in the range [0, n - 1] and swap the values of nums1[i] and nums2[i]. Your task is to find the minimum number of operations required to satisfy the following conditions: Return an integer denoting the minimum number of operations needed to meet both conditions, or -1 if it is impossible to satisfy both conditions.
