Input Output Questions and Answers

Answer: D

Correct answer: cannot be determined

Every step of these machines moves one element to a fixed position and lets the rest close up behind it, so the original positions of the elements still waiting are lost as soon as the first move is made. The process runs one way only: from a later line you can say what will follow but never what came before, because many different inputs produce the same intermediate line. That is why the answer to any “what was the input” question of this kind is that it cannot be determined.

Answer: B

Correct answer: 36 Uniform 41 train 61 horse 81 king

The placement order is 36, Uniform, 41, train, 61, king, and the machine prints a step only when something actually moves. Step I brings 36 to the front; Uniform is then already in position two, so step II brings 41 to position three; train is already in position four, so step III brings 61 to position five, giving 36 Uniform 41 train 61 horse 81 king.
