 
SPEAKER 1: When the function, size, is
called, size should return the number
of words that are in your given
dictionary data structure.
>> So if you're using a hash table, you
can either go through every single
linked list in every single bucket,
counting the number
of words are there.
>> If we're using a Tri, you can
go through every non-null
path in your Tri.
Or, while you're loading the dictionary
in, maybe you can keep
track of how many words
you're loading in.
