LomutoPartition

Hoare partition

Quicksort

• Lomuto:
  QuickSort(A, p, r - 1)
QuickSort(A, r + 1, q)

• Hoare:
  QuickSort(A, p, r)
QuickSort(A, r + 1, q)

So your statement is correct: for Hoare, the first recursive call uses p, r instead of p, r - 1.

The reason is:

• in Lomuto, r is the pivot’s final position, so exclude it

• in Hoare, r is only the split boundary, so include it in the left side

One warning: this is true only if your Partition is actually a Hoare partition. If you use Hoare partition but still recurse with r - 1, you can skip elements or break the algorithm

Time Complexity

Basically if you end up with small o that directly implies big O since small o is tighter and the way that you would write it is F(n) is an element of o(g(n))
