Solving the puzzle logically
The user provided a puzzle with several clues to solve for a three-digit lock code.
I see that clue 4 tells me digits 1, 2, and 4 aren't in the code. With clue 1, we know that one of 3, 1, or 8 is correct and in the right spot. From that, I can discard 1 entirely and focus on possibilities for 3 and 8. I'll keep working through the clues to logically eliminate and narrow down the correct code.
Narrowing down possibilities
From my reasoning, since 1 isn't in the code, the only possible correct digits from clue 1 are 3 or 8. Whichever is correct must also be in the right position. If 3 is correct in position 1, then 8 can't be in the code. Looking at clue 3, I know that two digits are correct but in the wrong places, which suggests digits 8, 6, and 3 could be part of the code but in different positions. I need to keep narrowing this down logic by logic.
Reevaluating assumptions and concluding code
In this step, I’m analyzing clue 3 and dealing with contradictions. Since we’ve already ruled 3 out, we know 6 must be the correct digit that's misplaced. We also know the code contains 8 at position 3 and that 6 isn’t in position 2. This leaves position 1 for 6. The clues indicate only two digits from {8, 6, 3} are correct, so 3 is absent. From there, we know 8 and 6 must be in the code, fulfilling the clues. The code is coming together!
