differents and intersections

# 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.
# Useset operations. The strings will always be in lowercase and will not contain any punctuation.
# Input1>>> "sharp" 
# Input2>>> "soap" 
# Output>>> ['aps', 'hr', 'o']
