A clear explanation of Wiggle Sort II using sorting, median splitting, and virtual indexing.
A clear explanation of finding the kth largest element using sorting, a min-heap, and Quickselect.
Select the k-th smallest element in an unsorted array using partitioning.
Find the k largest elements using partition-based selection in linear time.
Quickselect with random pivot selection to achieve robust expected linear time.
Find the element at a given rank using quicksort's partition step but recursing into only one side, achieving expected linear time.
