ROT13 Encoder / Decoder

Apply the ROT13 cipher to text — each letter is replaced by the letter 13 positions after it in the alphabet. Since the alphabet has 26 letters, applying ROT13 twice returns the original text, making the same function work for both encoding and decoding.

Input

Output

Uryyb, Jbeyq! Guvf vf n frperg zrffntr.

ROT13 is its own inverse — encode and decode use the same operation.
