1. Write a function that counts the occurrences of a word in a string. The function should return an integer. Do not assume that just one space separates words and a string can contain punctuation. Write the function so that it works with either a String argument or a StringBuilder object.

2. Write a function that takes a number, such as 52, and returns the number as a word, as in fifty-two.
