Study the following information to
answer the questions given below:
A number arrangement machine when given an input
Of numbers, rearranges them following a particular rule in
each step. The following is an illustration of input and steps
of rearrangement.
`{:("Input : 48 245 182 26 99 542 378 297"),("Step I : 542 48 245 182 26 99 378 297"),("Step II.: 542 26 48 245 182 99 378 297"),("Step III :542 26 378 48 245 182 99 297"),("Step IV :542 26 378 48 297 245 182 99"),("Step V.: 542 26 378 48 297 99 245 182"):}`
(This is the final arrangement and Step V is the last step for this input.)
How many steps will be required to get the final output
from the following input ?
Input : 39 88 162 450 386 72 29

Options

A. Two
B. Three
C. Four
D. Six

Answer

D

Explanation

After analysing the sample sequence, the pattern/rule in
each step for a number arrangement is as follows :
First step : Largest number comes to the left most position.
The remaining numbers shifts rightwards.
Second step : Smallest number shifts to the second
position. The remaining numbers shifts right words as so on.
So, the numbers are arranged as : largest, smallest, second
largest, second smallest, ....... and so on OR in descending
order and in an ascending order alternately.
Note : At each step, position of only. one number is altered.
