Please add the following to my class in the code and don't make a sepearte one

Question: Implement the following functions in your class: getTotalWords (returns the amount of total words), getUniqueWords (returns the amount of unique words), getMostUsedWord, (returns the word that is most used) getMaxOccurrence (returns how many times the most used word occured). Name them as indicated here.

The code to add the functions to:
