adeterministic finite automaton although the symbol on each edge is often implicit in the order of the branches It is not necessary for keys to be explicitly stored in nodes  In the figure words are shown only to illustrate how the trie works  Though tries are most commonly keyed by character strings they don‘t need to be The same algorithms can easily be adapted to serve similar functions of ordered lists of any construct eg permutations on a list of digits or shapes In particular a bitwise trie is keyed on the individual bits making up a short fixed size of bits such as an integer number or memory address In the example shown keys are listed in the nodes and values below them Each complete English word has an arbitrary integer value associated with it A trie can be seen as
