#this function is for getting correct position of pivot

        while left<=right and list1[right] >= pivot:

        if right < left :
            break
        else:
            list1[left],list1[right] = list1[right],list1[left]
    list1[first],list1[right] = list1[right],list1[first]

    return right
def quicksort(list1,first,last):
    if first < last :
        p = pivot_place(list1,first,last)

quicksort(list1,0,n - 1)
print(list1)
