Array Difference Coding Problem | Dataford Interview Questions

Given two arrays, print out the numbers in the first array that are not in the second.

Implement find_missing(nums1, nums2). Return a new array containing every occurrence from nums1 whose value does not occur in nums2, preserving the order from nums1. Return an empty array when no values qualify.

Constraints

1 <= len(nums1), len(nums2) <= 100000
-10^9 <= nums1[i], nums2[i] <= 10^9
Preserve the order of values from nums1
Preserve duplicate occurrences from nums1

Function Signature

def find_missing(nums1, nums2):
