8.26 LAB: Word frequencies (dictionaries)

Implement the build_dictionary() function to build a word frequency dictionary from a list of words.

Ex: If the words list is:

["hey", "hi", "Mark", "hi", "mark"]

the dictionary returned from calling build_dictionary(words) is:

{'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1}

Ex: If the words list is:

["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"]

the dictionary returned from calling build_dictionary(words) is:

{'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1}

The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value.

Ex: If the input is:

hey hi Mark hi mark

the output is:

Mark: 1 hey: 1 hi: 2 mark: 1

Use Python, please.
