Find the 10 most common and 10 least common words in the textfile.
Find the 10 most common and 10 least common bigrams in the file. (A bigram is two words following each other in the text. (F.ex. "The red fox" contains 2 bigrams: "The red" and "red fox". - See )
Find the longest phrase that also appears at least twice.
("longest phrase" here means the number of words, NOT letters)

Please tell us what you have done so far. Please tell us *exactly* what issue you are running into. We can't help you if we don't know where you are stuck.
