Taco String Encryption

You are given a string s consisting of lowercase letters ('a'-'z') and an integer k. For each character in s, you need to shift it forward by k positions in the alphabet. The alphabet wraps around at z so that, for example, shifting z by 1 gives a. In mathematical terms, if you consider the position of a letter c as an integer from 0 to 25, then the new letter is calculated as

$$ new\_index = (index(c) + k)\mod 26 $$

Your task is to output the encrypted string after applying the shift to every character.

inputFormat

The input consists of two lines:

• The first line contains a string s consisting only of lowercase English alphabets.
• The second line contains an integer k which represents the number of positions to shift each character.

Output the encrypted string after shifting every character of s by k positions. The transformation wraps around such that after z it restarts at a.
