A password policy requires at least 8 characters and at least one digit. What is the minimum length required?

Explanation:
The key idea is that the minimum length is set by the stricter length requirement. The policy says the password must be at least 8 characters long and must include at least one digit. The length rule requires you to have 8 or more characters, and the digit rule only restricts content, not length. So you can satisfy both with a password that is exactly 8 characters long and includes a digit somewhere within it. That makes the minimum length eight. Shorter options like six or seven fail the length requirement, while nine would also satisfy both but isn’t the smallest possible.
