Alphabet Shift Cipher

You are given a string message and an integer n. Your task is to shift each alphabetical character in the string by n positions in the alphabet. The shifting should wrap around the alphabet; that is, after 'z' comes 'a' and after 'Z' comes 'A'. Non-alphabetical characters (such as punctuation, spaces, digits, etc.) should remain unchanged. Both uppercase and lowercase letters must be handled appropriately.

For example, when shifting "abc" by 2, the result is "cde"; when shifting "XYZ" by 1, the result is "YZA".

Note: The shifting should follow the Caesar cipher technique.

inputFormat

The input consists of two lines:

• The first line contains a non-empty string message that may include spaces and punctuation.
• The second line contains a single integer n representing the shift amount.

Please read the input from stdin.

Output a single line which is the resulting string after shifting the letters in message by n positions. Write your answer to stdout.
