A number-arranging machine moves one number per step: in each step the smallest number not yet fixed is shifted into the rightmost free position, while the other numbers keep their relative order. Example - Input: '32 14 25 41'. Step I: '32 25 41 14'. Step II: '32 41 25 14'. For the input '46 29 53 18 37', which line is Step I?
