I've taken a look at this questions , but I still don't see the difference between a Suffix tree and a Trie .
Both have all the substrings of a given string , so where do they differ from one ano...

I have been reading a bit about tries, and how they are a good structure for typeahead designs. Aside from the trie, you usually also have a key/value pair for nodes and pre-computed top-n suggesti...

I'm not too well-versed about the actual algorithms used in string matching with tries.
I'm wondering why there seems to be more focus on suffix tries for string matching rather than prefix tries....

What is the best/worst/average case complexity (in Big-O notation) of a trie data structure for insertion and search?
I think it is O(K) for all cases, where K is the length of an arbitrary string...

I remotely remember that tries don't store the whole data per node, only the suffix to the parent node.
Where trees do store the whole data, but only organize themselves based on a prefix.
So tri...

One of my favourite data structures in college was the Trie. It's a great data structure for holding a large set of strings if the prefixes are shared. Lookups are also nice, since they are done at...
