A lock's passcode is composed of three digits. Five incorrect passcodes are given below, each with a hint to the correct passcode.

2-0-6: Two of the digits are correct but are in the wrong places.

6-1-4: One of the digits is correct but is in the wrong place.

6-8-2: One of the digits is correct and is in the right place.

7-8-0: One digit is correct but is in the wrong place.

7-3-8: None of the numbers is correct.


Can you deduce the lock's passcode?
