Find

(algorithm)

Definition: An algorithm to select the kth smallest element of an array and partition the array around it. First, partition around the value of the kth element. If the split is not at element k, move the upper or lower boundary and partition again.

See also select and partition, MODIFIND, Select.

Note: This does more swaps than MODIFIND.
