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 interchangedStep 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 81Step 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 81Step III: 91 23 11 21 64 63 98 14 65 35 57 18Step IV: 92 13 12 11 66 43 91 84 63 55 51 78Thus, 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.
