Change the program so that it outputs the percentage of uppercase characters (A-Z), the percentage of lowercase characters (a-z), and the percentage of digits (0-9) in the text file. Note that these percentages will NOT add up to 100! For example, in the highlighted purpose sentence above, there are 83 characters: 3 upper case, 61 lowercase, 1 digit, plus spaces and punctuation. Your program should just print a message like this:

There are 83 characters, with 3.61% upper case, 73.49% lower case and 1.20% digits.
