 # function that accepts 2 arrays. 
 # The arrays contain numbers and each input array is already sorted in increasing order. 
 # The function should create and return another array which contains all of the numbers that are in the 2 input arrays. 
 # The numbers in the returned array should also be sorted in increasing order
 # Example usage: python process_numbers.py [1,10,3,22,23,4,2,200,201,202,203,204,205,206,207,207,209] [5,8,9,11,25]
