I have to write a program that reads in from a data file. Then, it is supposed to pick out the words of a certain length. Once it finds these words, it places the words in two lists. One lists contains the words and the number of occurrences sorted alphabetically, and the other list contains the same info just sorted my most occurrences. I am to use a node class which I can write anyway that I want. However, I am confused about how to write it. Can someone help me?
