Consider an array consisting of the following elements in unsorted order (placed randomly), but 60 as first element:
60, 80, 15, 95, 7, 12, 35, 90, 55
Quick sort partition algorithm is applied by choosing first element as pivot element. How many total number of arrangements of array integers is possible preserving the effect of first pass of partition algorithm?
    Correct answer is '720'. Can you explain this answer?

    The effect of the partition algorithm when a pivot is P: After the Partition algorithm, P will go to its correct position and all the elements less than or equal to P will go to one side and all the elements greater than P will go to the other side.
    We have to choose the first element as a pivot:
    Here 60 is given as the first element.
    After the first pass, the pivot element goes to its exact location.
    Here 60 goes to 6th place.
    All the elements less than 60 go to left of 60 and all the elements greater than
    60 go to right of 60.
    After 1st  pass.

      ⇒ 5! × 3!
    = 720 possible arrangements.
    Hence, the correct answer is 720.
