# INSTRUCTION
# Implement the unique_names method. When passed two arrays of names, it will return an array containing the names that appear in either or both arrays. The returned array should have no duplicates.

# For example, calling unique_names(["Ava", "Emma", "Olivia"], ["Olivia", "Sophia", "Emma"]) should return an array containing Ava, Emma, Olivia, and Sophia in any order.

def unique_names(names1, names2)
  return (names1 + names2).uniq
end

names1 = ["Ava", "Emma", "Olivia"]
names2 = ["Olivia", "Sophia", "Emma"]
puts(unique_names(names1, names2)) # should print Ava, Emma, Olivia, Sophia
