4. A password to a vault must have at least 8 characters where each character can be an English alphabet (case sensitive) or a digit. A hacker observes a user inserting the password and based on the time taken to insert the password, the hacker is rest assured that the password is no longer than 11 characters. If the hacker can try a million permutations per second, how long will it take to try all possible passwords?
