Encrypting Messages with a Shift Cipher

You are given a string message consisting of lowercase English letters and an integer shift. Your task is to encrypt the message using a Caesar cipher. For each character in the message, shift it by the given number of positions in the alphabet. If the shift goes past 'z', it wraps around to 'a'.

The transformation for each character ch is given by:

$$ new\_char = 'a' + ((ch - 'a' + shift) \mod 26) $$

Write a program that reads the message and shift from standard input and prints the encrypted message to standard output.

inputFormat

The input consists of two lines:

• The first line contains the string message (only lowercase letters).
• The second line contains an integer shift which represents the shift value.

outputFormat

Output the encrypted message as a single string.
