+"""Write a program that takes two inputs; one of them is a list and the other is a number, and returns the list obtained by shifting the elements in the list n places to the right (left) when n is positive (negative). Use wrap-around: if an element is shifted beyond the end of the list, then continue to shift starting at the beginning of the list.

+Write a code snippet that inputs a sentence from the user, then uses a dictionary to summarize the number of occurrences of each letter. Ignore case, ignore blanks and assume the user does not enter any punctuation. Display a two-column table of the letters and their counts with the letters in sorted order.

+Write a program that takes in two words as input and returns a list containing three elements, in the following order:
+-		Shared letters between two words.
+
+-		Letters unique to word 1.
+
+-		Letters unique to word 2.
+
+Each element of the output should have unique letters, and should be alphabetically sorted. Use set operations. The strings will always be in lowercase and will not contain any punctuation.
