numbers $=[17,13,19,29,28,36,69,49,51,55]$

Partition$($numbers$,5,9)$ is called. So$,$ only elements in indices $5$ to $9$ are partitioned.

Elements in indices $0$ to $4$ are not affected.

Assume quicksort always chooses the element at the midpoint as the pivot.

What is the pivot?

What is the low partition?

$]($comma between values$)$

What is the high partition?

$]$

What is numbers after Partition$($numbers$,5,9)$ completes?

$]($Elements in indices $0$ to $4$ stay the same.$)$
