Oh no! My strings have been mixed up. Each pair of letters has been swapped.
Here are examples: "eHllo" should be "Hello". "lCjorue" should be "Clojure".
Write a function to unmix these strings. If the length of the string is odd, the last character is not altered.
(unmix "aHpp yeN weYra !eS eoy uni2 20 0):")
Implement and run the line above to decode the secret message!
Thanks to to this site for the challenge idea!
