A PATRICIA trie is a special variant of the radix 2 (binary) trie, in which rather than explicitly store every bit of every key, the nodes store only the position of the first bit which differentiates two sub-trees. During traversal the algorithm examines the indexed bit of the search key and chooses the left or right sub … See more In computer science, a radix tree (also radix trie or compact prefix tree or compressed trie) is a data structure that represents a space-optimized trie (prefix tree) in which each node that is the only child is merged with … See more Radix trees support insertion, deletion, and searching operations. Insertion adds a new string to the trie while trying to minimize the amount of data stored. Deletion removes a … See more (In the following comparisons, it is assumed that the keys are of length k and the data structure contains n members.)
