# 1
# write a function that takes a word as a parameter and returns a scrambled version of the word 




# 2
# write a function that takes in a word and returns an 'encrypted' version by increasing each letter by 2 (e.g. 'a' becomes 'c', 'f' becomes 'h', etc.)



# 3
# write a function that decodes the 'encrypted' version of the word into its original form (the opposite fo the above challenge problem)
