Question: Consider the following implementation of partition from the quicksort algorithm that was covered in lecture. Note that the last element in the array is chosen

Consider the following implementation of partition from the quicksort algorithm that was covered in lecture. Note that the last element in the array is chosen as the pivot.
int partition(int a[], int left, int right){
int pivot =--right;
while (true){
while (a[left]< a[pivot])
++left;
while (left < right && a[right -1]>= a[pivot])
--right;
if (left >= right)
break;
swap(a[left], a[right -1]);
}
swap(a[left], a[pivot]);
return left;
}
Suppose that you had the following unsorted array:
int[] arr ={88,34,77,20,53,45,12,76,29,61};
What are the contents of this array afterone call to partition(arr,0,10)?
