I'm learning Rust and one of the challenges in the book was to build a pig latin translator.
Convert strings to pig latin. The first consonant of each word is moved to the end of the word and “ay” is added, so “first” becomes “irst-fay.” Words that start with a vowel have “hay” added to the ...

You wish to send a secret letter to your friend. Suspecting your parents have a tendency to read letters not intended for them, you decide on a coding scheme. Each letter is converted to the letter which is 3 places after it in the alphabets. For example, A is converted to D. The sequence is cycl...
