You get a text. It is a reminder from your dentist’s office that you have an appointment tomorrow. It says to type “1” to confirm or “2” to cancel the appointment. You accidentally type a “3” and nothing happens. How could the input validation be improved?

Answer:

Redo the one you want

Explanation:

Redo the "1" if you are confirming the appointment

Or "2", if you do not.

Do not fret over this worse, comes to worse call your dentist back and explain you hit the 3 by mistake and then tell them your decision .
