Unioning two arrays

Python Algorithms Data Structures

Forward this email to a friend or colleague and challenge them to solve it.

Hi, 

Given array A containing N elements and array B containing M elements, write a Python function that returns a union between arrays A and B. If array A and B have duplicate elements, you'll only need to add the duplicate element once.

For example:

    

[1, 2, 3, 4], [1, 3, 5, 7, 10] -> [1, 2, 3, 4, 5, 7, 10]

[1, 2, 3], [4, 5, 6] -> [1, 2, 3, 4, 5, 6]

Our solution will be written in Python for premium users.
