e) There will be no such step


The machine rearranges the words and numbers in such a way that the words are arranged according to the length of words in descending order from left end. Words of the same length are arranged in reserve English alphabetical order, while numbers are arranged in ascending order on the right end in each step.

Input: toy  18  till  24  36  is  of   never  87  99  cut  73
Step I: never   toy  till  24  36  is  of   87  99  cut  73  18
Step II: never  toy  till  36  is  of   87  99  cut  73  18  24
Step III: never  toy  till  cut  is   of  87 99 73  18  24  36
Step IV: never  toy  till cut  of   is  87  99  18  24  36 73
