(classic problem)
Definition: Find the kth smallest element of a set. Two approaches are a modified distribution sort or select and partition.
Also known as selection problem, find kth least element, kth smallest element.
See also Select, MODIFIND, Find.
Note: The select-and-partition approximately divides in half the number of elements which must be considered at each step. The modified distribution sort divides by m the number of elements at each step. The latter is faster, but the former is more generally applicable.
