The goal here is to accept input from the user and create a list. Then you will add the elements of the list to a set. If the set size increases, add the word to a dict with the word being a key and the value being the length of the set, which is also the number of
pairs in the dict at the time it was added. In psuedocode, you will need something like:
for each word in the input text:
set a variable equal to the length of the set
add word to the set
if the length of the set is greater than the length of the "old" set:
add the word to the dict
for k, v in words.items():
print(k, v)
