I really wanted to talked to her,but my English was so poor and she was not a national god but a foreign one...After thirty minutes,she flew away...but story was not finished here,she had left a letter for me!!!What puzzled me so much is the letter was encoded.I had thought for many days,but still can't get it. Now I turn to you for help,with some limited prompts,can you help me to decode the whole letter?

CN WLP JRVMFGQ BVR,IJCFI? -> DO YOU REQUIRE AID,HUMAN?
NMAB VYNNF, FI'E VC HP IXJ ZLQZI. -> ONCE AGAIN, IT'S UP TO THE ELVES.
...

 

Input

Each case is one line of string with uppercase letters and white spaces and other symbols.
