A man wanted to work but he could not log in to his computer terminal successfully. He tried twice but his password didn’t work. He suddenly remembered that the passwords are reset every month for security purposes. So he called his boss and said,
Man-“Hey boss, my password is out of date.”
Boss-“Yes, that’s right. The password is different, listen carefully, I am sure, you can figure out the new one. The new one has the same amount of letters as your old password, but only four of the letters are the same.”
Man: “Thanks boss.” With that he could correctly log into his station. Can you tell me his new and old passwords?
