A missing employee left behind one strange file on an abandoned workstation. Investigators recovered a small program that asks for a four-digit case code. The correct code supposedly unlocks the employee's final note. "Some locks aren't meant to be picked. They're meant to be tried, over and over, fast."

During an archaeological excavation, researchers uncovered a notebook claiming to belong to a traveler from the year 2140. Most of the journal is unreadable, but one page contains hundreds of numbers arranged in sequence. According to the author's notes, the numbers aren't random—they represent a message meant to be reconstructed by a simple computer program. The traveler left one final note: Some messages are meant to be automated, not read one digit at a time. Can you recover the hidden message?
