Questions relating to machine input-output or simply input-output are a series of statements in different steps and is stated in jumbled manner. It is a kind of computer or word-processing machine and this machine performs some operations on the input that is given. The machine operates repeatedly according to a predetermined pattern.

These types of questions are normally asked in reasoning topics. These questions may look tough but actually they are very easy. We have to just look the input line and compare it with the end step line and after comparison we can make an idea of the machine’s performance. After plotting the idea, we can start from the first step to understand the orientation of the steps.

Given an input line a machine generates pass codes step by step following certain rules as illustrated below.

Step I 95 13 67 84 76 18 38 78

Step II 95 84 13 67 76 18 38 78

Step III 95 84 78 13 67 76 18 38

Step IV 95 84 78 76 13 67 18 38

Step V 95 84 78 76 67 13 18 38

Step VI 95 84 78 76 67 38 13 18

Step VII 95 84 78 76 67 38 18 13
