🧠 Before you code — what pattern fits?
Given two integer arrays nums1 and nums2, return a list answer of size 2 where answer[0] is a list of all distinct integers in nums1 not present in nums2, and answer[1] is a list of all distinct integers in nums2 not present in nums1.
([1,2,3],[2,4,6]) → [[1,3],[4,6]]
