From Clues 1 + 2 we know that 6 is not in the answer. Therefore with clue 3 we know that the correct answer includes 2 and 0 but in different positions. Therefore from clue 1 we know that 8 is not in the answer and #2 must be in position 3. (? ? 2). Therefore from clue 3 we know that 0 must be in position 1 (0 ? 2). Therefore from clue 2 we know that number 4 must be in position 2, so the answer is (0 4 2).
Each time we get an extra bit of information we need to go back and read each of the hints again.
