You are given two arrays of integers as arguments. Merge the two arrays into a single array sorted in ascending numerical order, with all duplicates removed.

Requirements

• Must return an array of integers
• Should also work with negative numbers

Example #1

solve([1,2,3,4],[8,9,2,4)
> [1,2,3,4,8,9]

Example #2

solve([-1,2,3,4],[1,8,9,2,4)
> [-1,1,2,3,4,8,9]
