Find the Difference of Two Arrays
Given two 0-indexed integer arrays nums1 and nums2, return a list answer of size 2 where: Note that the integers in the lists may be returned in any order.
Given two 0-indexed integer arrays nums1 and nums2, return a list answer of size 2 where:
Note that the integers in the lists may be returned in any order.
Example 1
Input: nums1 = [1,2,3], nums2 = [2,4,6]
Output: [[1,3],[4,6]]
Explanation: For nums1, nums1[1] = 2 is present at index 0 of nums2, whereas nums1[0] = 1 and nums1[2] = 3 are not present in nums2. Therefore, answer[0] = [1,3]. For nums2, nums2[0] = 2 is present at index 1 of nums1, whereas nums2[1] = 4 and nums2[2] = 6 are not present in nums1. Therefore, answer[1] = [4,6].
Example 2
Input: nums1 = [1,2,3,3], nums2 = [1,1,2,2]
Output: [[3],[]]
Explanation: For nums1, nums1[2] and nums1[3] are not present in nums2. Since nums1[2] == nums1[3], their value is only included once and answer[0] = [3]. Every integer in nums2 is present in nums1. Therefore, answer[1] = [].
Constraints
- 1 <= nums1.length, nums2.length <= 1000
- -1000 <= nums1[i], nums2[i] <= 1000
