Answer: C) Four
A number-arrangement machine rearranges an input line in steps. In each step it moves the largest number that is not yet in its final position to the rightmost available place, shifting the others left; this repeats until the whole line is in ascending order. Input: 15 47 23 08 39 12. Step I: 15 23 08 39 12 47. Step II: 15 23 08 12 39 47. How many steps are needed to complete the arrangement?
