The Runtime of quicksort on data with these patterns are
PARTITION(A, p, r)
x = A[r]
i = p-1
for j = p to r-1
if A[j]≤x
i=i+1
exchange A[i] with A[j]
exchange A[i+1] with A[r]
return i+1
What does quicksort mean?
A divide-and-conquer algorithm is a quicksort. It operates by choosing one element from the array to serve as the "pivot," and then dividing the remaining components into two sub-arrays based on whether they are less than or greater than the pivot.
What does Quicksort's partition function do?
Partition guarantees that all things less than the pivot come before it and then give the pivot's position back. All the elements in the lower half are known to be less than the pivot, and all the items in the upper half are known to be greater than it, so this satisfies our need for partitioning the problem.
Hence, partition() is used to organize two partitions.
