Step-by-Step Solution

A word-and-number arrangement machine rearranges any input line in steps. In each step two shifts happen together: the smallest number that has not already been shifted in an earlier step is taken out and placed at the extreme right end of the line, and at the same time the word that comes first in alphabetical order among the words not already shifted in an earlier step is taken out and placed at the extreme left end of the line. All the remaining elements keep their relative order, and the machine stops when no further shift is possible.
