Every Twenty-Fifth

Description

A secret message is hidden inside a block of text using position-based steganography.


Method: Count only the alphabetic characters (A–Z), ignoring spaces and all punctuation. Every 25th alphabetic character (positions 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300) is part of the hidden message.


The block contains exactly 300 alphabetic characters, producing a 12-character hidden message.


Your task: Extract the hidden message (uppercase).


Answer format: 12 uppercase letters, no spaces.
