What will be the output of the step II?

The logic is as follows:

Step I: The first two smallest numbers are arranged in ascending order.

Step II: The next two smallest numbers are arranged in ascending order shifting the previously arranged one inward.

Step III: The digits of all the numbers are interchanged

Step IV: Taking a pair of numbers from the left-most side, the first two digits of the number pair are taken to form a number. Similarly, the second two digits of a number pair are taken to form the next number.

Input: 12  46  32  11  19  36  89  41  56  53  75  81

Step I: 11  12 46  32  19  36  89  41  56  53  75  81  

Step II: 19  32  11  12  46  36  89  41  56  53  75  81

Step III: 91  23  11  21  64  63  98  14  65  35  57  18

Step IV: 92  13  12  11  66  43  91  84  63  55  51  78

Thus, Step IV is the last step.

Hence, 19  32  11  12  46  36  89  41  56  53  75  81 is the Step II of the given input.
