Consider the following array.
Which algorithm out of the following options uses the least number of comparisons (among the array elements) to sort the above array in ascending order?
  • a)
    Selection sort
  • b)
    Mergesort
  • c)
    Insertion sort
  • d)
    Quicksort using the last element as pivot
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Consider the following array.Which algorithm out of the following opti...
Since, given array is almost sorted in ascending order, so Insertion sort will give its best case with time complexity of order O(n).
