Background:

You recently started writing up some of your favorite short stories and scripts on your computer, but since you have started working with celerys *cough cough* I mean cell arrays in MATLAB, they have been corrupted! Oh no! Now, you must embark on an epic quest to use the very same piece of software that corrupted your files to analyze your files.

Function Description:

You will be given a text file. Extract every unique word and count the number of times each unique word appears in the text file. Case should be ignored when looking for unique words, and any characters that are not letters or spaces should be removed. The words should appear in decreasing order of how often they appeared in the text file. If there is a tie, you should sort the ties alphabetically. To make the output text file, follow these rules:

The output text file should have the name _counted.txt .

The output file should start with 'A counting of the story :'.

The second line should read 'The number of times celery was seen:

celery>' .

The third line should read 'All other words:' .

The rest of the file should list the unique words in the following form: ':

times>' .

Each word should be lowercase.

Put each word on a new line.

Do not include the word "celery" in this section.

Example:

twinkle.txt: twiNk)(le twinKLe# li,ttle celery H34ow i ce//lery wh*at you are 

twinkle_counted.txt: A counting of the story twinkle: The number of times celery was seen: 2 All other words: twinkle: 2 are: 1 how: 1 i: 1 little: 1 what: 1 you: 1 

Notes :

There should NOT be a newline character at the end of your text file.

All the words in the text file should be lowercase.

Hints : sort() preserves the original order of duplicated elements. In order to sort by two

things, think about how you could use the sort() function twice.
