Equal Sum Arrays with Minimum Number of Operations
Given two arrays nums1 and nums2 of dice values 1–6, where one operation changes any single value in either array to any value from 1 to 6, return the minimum number of operations that makes the two sums equal, or -1 if that is impossible.
Examples
Example 1
[1,2,3,4,5,6] vs [1,1,2,2,2,2]Output: 3 ops
Example 2
[1,1,1,1,1,1,1] vs [6]Output: -1 (impossible)
