A word arrangement machine when given an input line of words, rarranges them following a particular rule in each step. The following is the illustration of the input and the steps of arragement:
Input : She was shot dead at, her residence
Step I : at was shot dead she her residence
Step II : at her shot dead she was residence
Step III : at her she dead shot was residence
Step IV : at her she was shot dead residence
Step V: at her she was shot dead residence
Since the words are fully arranged, the machine stops. Otherwise it may go on till the words get fully arranged. Study the logic and answer the questions.
