Letter Counts Using Dictionaries

Remember to consider spaces as a special case.

(a)    Write a function that takes as input a string and returns the most common letter in the string

(b)   Write a function that takes as input a string and returns a dictionary of letter counts.

(c)    Write a function that takes as input a string and prints a histogram of letter counts.
