Study the following information carefully to answer the questions given below. In a toy exhibition, a machine processes a given input by the following rule. Participants are shown one by one till it reaches its last step. Following is an illustration of the working of this machine.
Input : sui me ato fe zen u no
Step I : fe sui me no ato zen u
Step II : no fe sui u me ato zen
Step III: u no fe zen sui me ato
Step IV: zen u no ato fe sui me
Step V : ato zen u me no fe sui
Which of the following correctly describes the ‘machine logic’ in generating various steps based on the given input?
In each step the fourth word becomes first word and the last word becomes fourth word and all other words shift one place rightwards except the third, which shifts two place rightwards.
In order to make things easier, let us represent the words digitally from 1 to 7. Then we have:
Input: 1 2 3 4 5 6 7
Step I: 4 1 2 7 3 5 6
Step II: 7 4 1 6 2 3 5
Step III: 6 7 4 5 1 2 3
Step IV: 5 6 7 3 4 1 2
Step V: 3 5 6 2 7 4 1
Step VI: 2 3 5 1 6 7 4
=> Ans - (C)
