There's a shorthand syntax when we just call one method on the block variable:

input.map(&:capitalize)

This means: call capitalize on each item in the array, without needing to name the element as we iterate through them ("x"). It's more "declarative" and generally preferred.

end

def fetch_the_dog(input)
#implement your solution here
input.select{|x| x == 'dog'}
end

def no_dogs_allowed(input)
#implement your solution here
input.reject {|x| x == 'dog'}
end

def count_the_animals(input)
#implement your solution here
input.count
end

def fetch_the_first_two(input)
#implement your solution here
input.take(2)
end

def fetch_CD_animals(input)
#implement your solution here
input.grep /cat|dog/
end
