WebIn trie tree, we have seen that each edge contains a single letter or single part of a key. Radix trees are like a compressed version of trie trees, where the edges can contain more than a single letter, even an entire word (if we are using them for words/letters). This is very effective, reducing the amount of memory and space the tree needs.

WebComparing height of radix trees with search trees. If comparing only the height, radix tree's height is k/s while search trees usually have log n base 2. Therefore you use radix trees when k/s < log n base 2 i.e. when 2^(k/s) < n. For the same given span s, radix trees and ART would have the same height, but the size of the nodes on every level ... Tries can be represented in several ways, corresponding to different trade-offs between memory use and speed of the operations.
