# linear probing sort

(algorithm)

**Definition:**
Distribute each of n elements to one of m locations in an array (m>n) based on an interpolation of the element's *key*. In case of *collisions*, put the element in the next empty location. The array has extra space at the end for overflow. The second pass packs the elements back into an array of size n.

**Generalization** (I am a kind of ...)

*distribution sort*.

**Aggregate child** (... is a part of or used in me.)

*linear probing*.

*Note:
The sort may fail if the overflow is exceeded. *

*
** The distribution phase may be seen as putting the elements in a **linear probing* *hash table* using the interpolation function as the *hash function*.
