Problem 724. QWERTY Shift Code Decoder

Decode a string encoded using the QWERTY shift code.

QWERTY shift code is where the message was touch typed but with an offset of one character to the right.

Only letters are encoded as the top row does not incur shifting.

(eg) "A" became "S" and "a" became "s"

"PpLlMm" became "{[:;<,"

An encoded message never contains any "QqAaZz" letters.

Illegal characters in the original message were "{[:;<,".

Decode "A-Za-z". All other characters are normal except for the Illegal characters.

Input:

encoded_str= "Upi ,odd"

Output:

decoded_str= "You miss"
