# 1 The remaining lines use the last 3 functions. sorted_words name is given the value of ex25.sort_sentence(sentence). The sentence is entered into the function where it uses the break function and the sort function. It is returned and becomes the value of the sorted_words name. Essentially, it just combined the first two function we wrote. The second function combins the break_words function and the two pop functions to show the first and last words in the list. The last function does the same thing but uses the sort_sentence function instead of break_sentence. It becomes clear at this point that the functions to not store anything in the argument name (no return)
