![def remove_duplicate_sorted(t):
this function returns a new list generated from t that has t's
elements without duplicates and is sorted from smallest to largest.
return []
def list_to_dictionary(t):
t is a list of values (values could be str, list, tuple, set, dictionary),
create and return a dictionary such that the key is len(v) for some v in t,
and the value is a list of values [v1, v2, ...] from t (in the order they
appeared in t) whose len(vi) is the key.
for example: if t = [(1,2,3), "abc", [1, 2], (), ""]
then return value of this function should be:
{3: [(1, 2, 3), 'abc'], 2: [[1, 2]], e: [(), "]}
return {}
def run():
This function repeatedly ask user to enter a string and store them in a
list and print it out.
It also passes this list to remove_duplicate_sorted() function and
list_to_dictionary() function and print out the results of the function
calls.
