Quick sort is run on two inputs shown below to sort them in ascending order:
Input (1) - 1, 2, 3, …… n
Input (2) - n, n – 1, n – 2, n – 3, …… 2, 1
Let C1 and C2 be the number of comparisons made for the inputs 1 and 2, respectively. Then,
  • a)
    C< C2
  • b)
    C1 > C2
  • c)
    C1 = C2
  • d)
    We cannot say anything for arbitrary n.
Correct answer is option 'C'. Can you explain this answer?

Quick sort is run on two inputs shown below to sort them in ascending ...
The input (1) is already sorted in ascending order, so quick sort will not make any changes to this input.

Quick sort is run on two inputs shown below to sort them in ascending ...
1, 2, 3, …… n
n, n – 1, n – 2, n – 3, …… 2, 1
Quick sort, for example, takes the worst time when the inputs are already sorted. For both inputs (1) and (2), the numbers of comparisons will be the same, i.e. C1 = C2.
