  • a)
    t1 =5
  • b)
    t1< t2
  • c)
    t1> t2
  • d)
    t1 = t2
Correct answer is option 'C'. Can you explain this answer?

Let P be a quicksort program to sort numbers in ascending order using ...
When first element or last element is chosen as pivot, Quick Sort‘s worst case occurs for the sorted arrays.
In every step of quick sort, numbers are divided as per the following recurrence.
T(n) = T(n-1) + O(n)
Correct answer is option C.

Let P be a quicksort program to sort numbers in ascending order using ...
The correct answer is b) t1 < />

In quicksort, the number of comparisons made depends on the arrangement of the elements in the input array. In the first case [1 2 3 4 5], the array is already sorted in ascending order. In this case, quicksort will only make n-1 comparisons, where n is the number of elements in the array. So, t1 = 5-1 = 4.

In the second case [4 1 5 3 2], the array is not sorted. In this case, quicksort will make more than n-1 comparisons because it needs to rearrange the elements. The exact number of comparisons will depend on the pivot selection and partitioning strategy, but it will be greater than 4.

Therefore, t1 < t2.="" />
