Second verse: same as the first! Let’s go ahead and make ourselves a lambda.



Create a lambda called first_half that checks if a hash value is less than (that is, earlier in the alphabet than) “M”. (No need to do anything with the crew hash yet.) Make sure to use a capital “M,” since we’ll be checking capitalized names! Because it will be checking a hash, your lambda should include |key, value| instead of just |value|.
