The program below initializes some string variables. Add a single print() statement at the end that uses string concatenation (the plus sign) to join the variable values and other pieces of quoted text to produce the output "The dog chases the cat who chases the bird".

The following example demonstrates the expected program output.

The dog chases the cat who chases the bird
Be careful to include spaces where needed in your quoted text so the output has a single space between each word.

dog = 'dog'

cat = 'cat'
bird = 'bird'

print("The " + dog + " chases the " + cat + " who chases the " + bird)
