Hash trie

From Wikipedia, the free encyclopedia

In computer science, hash trie can refer to:

  • Hash tree (persistent data structure), a trie used to map hash values to keys
  • A space-efficient implementation of a sparse trie, in which the descendants of each node may be interleaved in memory. (The name is suggested by a similarity to a closed hash table.) [1][verification needed]
  • A data structure which "combines features of hash tables and LC-tries (Least Compression tries) in order to perform efficient lookups and updates" [2]
