Tries

Tries. Trees of order >= 2 Variable length keys The decision on what path to follow is taken based on potion of the key Static environment, fast retrieval but large space overhead Applications : dictionaries text searching (patricia tries) compression (Ziv-Lembel encoding). Example.

Tries

Tries. Definition. A trie is an index structure that is particulary useful when key values are of varying size. Trie is a tree of degree m >= 2 in which the branching at any level is determined not by the entire key value, but by only a potion of it.
