Create an implementation of the rotational cipher, also sometimes called the Caesar cipher. The Caesar cipher is a simple shift cipher that relies on transposing all the letters in the alphabet using an integer key between 0 and 26. Using a key of 0 or 26 will always yield the same output due to modular arithmetic. The letter is shifted for as many values as the value of the key. The general notation for rotational ciphers is ROT + . The most commonly used rotational cipher is ROT13. A ROT13 on the Latin alphabet would be as follows:

Plain: abcdefghijklmnopqrstuvwxyz

Cipher: nopqrstuvwxyzabcdefghijklm

Cipher text is written out in the same formatting as the input including spaces and punc-tuation. Develop a function called rotate that takes two arguments, first, the original text to be transformed, and second, the rotation key. The function should return the ci-phered text. For example, calling rotate(O M G, 5) should return T R L and calling rotate(Lets eat, Grandma!, 21) should return Gzon zvo, Bmviyh"
