Ternary search trees and ternary sequence search trees are defined as natural extensions of the binary case. Ternary tree insertion and its relation to topological sorting is also considered as a natural generalisation of binary tree insertion with its relationship to complete sorting. The problem of quasi-topological sorting.

Ternary logic is possible by using null as the third possible value that may be assigned to fields of this type. Note. The next several examples are not meant for you to.
