Shift Characters

You are given a string s consisting of ASCII characters. For every alphabetical character in s, replace it with the next character in the ASCII table. If the character is 'z' or 'Z', it should wrap around to 'a' or 'A', respectively. All non-alphabetical characters must remain unchanged.

The transformation can be expressed using the formula: if c is a character such that \( \text{ord}(c) \) represents its ASCII code, then for lowercase letters:

\( c' = \begin{cases} \text{chr}(\text{ord}(c)+1) & \text{if } c \neq 'z' \\ 'a' & \text{if } c = 'z' \end{cases} \)

and similarly for uppercase letters. Your task is to implement this transformation.
