Which of the following is the last step for the following input?

Options

  1. A432, 28, 309, 52, 127, 47, 116, 87
  2. B432, 28, 309, 47, 52, 127, 116, 87
  3. C432, 28, 309, 47, 127, 52, 116, 87
  4. D432, 28, 309, 47, 127, 116, 52, 87

Correct answer

C. 432, 28, 309, 47, 127, 52, 116, 87

Step-by-step solution

Here the rule followed is: The numbers are getting arranged in alternate series; one in descending order and the other in ascending order. Step I: The largest of the given numbers comes to the place of first number and the rest shift rightward. Step II: The smallest of the given numbers comes to the place of second number and the rest shift rightward. Step III: The second largest of the given numbers comes to the place of third number and the rest shift rightward. Step IV: The second smallest of the given numbers comes to the place of fourth number and the rest shift rightward and so on until the alternate series is formed. Input: 47,432,127,52,309,87,28,11647,432,127,52,309,87,28,116 In such case the final step can be written directly. 432,28,309,47,127,52,116,87432,28,309,47,127,52,116,87
