Mirror Word Checker

This problem is about checking whether a given string is a "Mirror Word". A string is considered a Mirror Word if all its characters belong to the set \(\{A, H, I, M, O, T, U, V, W, X, Y\}\) and the string reads the same forwards and backwards (i.e. it is a palindrome).

For example, the string "AHA" is a Mirror Word because:

• Every character is in the allowed set: A, H, A.
• The string "AHA" is a palindrome.

If both conditions are satisfied, output Mirror!!, otherwise output NOT!!.

Note: An empty string is considered a Mirror Word.

The input consists of a single line containing a string (s) composed of uppercase alphabetic characters. The string may be empty.
