# INSTRUCTIONS:

# Create a function named createArray. This function should:
#   1. Define a method named countries_visited.
#   2. The method should return an Array of the countries in alphabetical order..
#   3. The method should return an Array without duplicate values.


# Tests Given:

describe "countries_visited" do
  it "returns a unique list of sorted countries if the array has elements" do
    arr = ["USA", "USA", "France", "Scotland"]
    expect( countries_visited(arr) ).to eq(["France", "Scotland", "USA"])
  end
  
  it "returns a unique list of sorted countries if the array has elements" do
    arr = ["USA", "Germany", "Denmark", "Germany"]
    expect( countries_visited(arr) ).to eq(["Denmark", "Germany", "USA"])
  end
end


# Starting Code:

def countries_visited
end


# Current Answer:

def countries_visited(countries)
  countries = ["France", "Scotland", "USA"]
  return countries
}
countries_visited(["USA", "USA", "France", "Scotland"])


# Student: I can pass 1 test, but not both. What am I doing wrong?
