A number-arranging machine rearranges a set of numbers. In each step it fixes one more number into ascending order starting from the left end (Step I fixes the smallest number at the 1st position, Step II fixes the next smallest at the 2nd position, and so on; the remaining numbers keep their relative order and shift right as needed). Input: 82 17 46 23 65 39. Step I: 17 82 46 23 65 39. What will Step III be?
