LeetCode ProblemMinimum Operations to Make Array Equal II
You are given two integer arrays nums1 and nums2 of equal length n and an integer k. You can perform the following operation on nums1: nums1 is said to be equal to nums2 if for all indices i such that 0 <= i < n, nums1[i] == nums2[i]. Return the minimum number of operations required to make nums1 equal to nums2. If it is impossible to make them equal, return -1.
