Alphabetic Shift Transformation

You are given a string s consisting of lowercase English letters and a positive integer k. Your task is to transform the string by shifting each character by k positions forward in the alphabet, wrapping around if necessary. Specifically, for each character c in the string, compute its new character using the formula:

$$new\_char = ((ord(c) - ord('a') + k) \mod 26) + ord('a')$$

For example, if s = "abcdef" and k = 3, then the resulting string is "defghi".

Note: You need to read input from stdin and output the result to stdout.

inputFormat

The input consists of two lines:

1. The first line contains a string s of lowercase English letters (1 to 50 characters).
2. The second line contains a positive integer k (1 to 100), representing the shift value.

outputFormat

Output a single line containing the transformed string after shifting each character by k positions.
