An odd number of toggles leaves the door in the open position; hence, only perfect square-numbered doors (e.g., 1, 4, 9, 16, ..., 100) remain open. Prime numbers (e.g., 2, 3, 5, 7) have exactly two divisors (1 and itself), which is a pair - the door remains closed.What's the answer to the door riddle?
