WebA PATRICIA tree is related to a Trie . The problem with Tries is that when the set of keys is sparse, i.e. when the actual keys form a small subset of the set of potential keys, as is very often the case, many (most) of the internal nodes in the Trie have only one descendant. This causes the Trie to have a high space-complexity. WebA trie will often implement 3 main functions: insert, delete, and search. Tries can offer additional functionalities, but we will keep it simple by only looking at the 3 main …
