Understanding the Minimum Operations to Make Array Equal I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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: Choose two indexes i and j and increment nums1[i] by k and decrement nums1[j] by k. In other words, nums1[i] = nums1[i] + k and nums1[j] = nums1[j] - k. 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.

Get real-time assistance for Minimum Operations to Make Array Equal II problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums1 = [4,3,1,4], nums2 = [1,3,7,1], k = 32In 2 operations, we can transform nums1 to nums2. 1st operation: i = 2, j = 0. After applying the operation, nums1 = [1,3,4,4]. 2nd operation: i = 2, j = 3. After applying the operation, nums1 = [1,3,7,1]. One can prove that it is impossible to make arrays equal in fewer operations.
nums1 = [3,8,5,2], nums2 = [2,4,1,6], k = 1-1It can be proved that it is impossible to make the two arrays equal.
Constraints
n == nums1.length == nums2.length2 <= n <= 1050 <= nums1[i], nums2[j] <= 1090 <= k <= 105How Interview Coder Helps with Leetcode Problems
