Hi,
I am planning to work in TRIE data structure for which I need a dictionary database or a text or word file containing the entire list of english words. It doesnt matter if the size is huge. Larger the better.

I'm attempting to implement a Patricia Trie with the methods addWord(), isWord(), and isPrefix() as a means to store a large dictionary of words for quick retrieval (including prefix search). I've read up on the concepts but they just aren't clarifying into an implementation. I want to know (in Java…

Hello everyone,
Which one is the structure that provides best performance results? Trie, Suffix Tree or Suffix Array? There are other equivalent structures?
What are good Java implementations of these structures?
Thanks for your answers.
Best Regards,

I have a trie which I am using to do some string processing. I have a simple compiler which generates trie from some data. Once generated, my trie won't change at run time.
I am looking for an approach where I can persist the trie in a file and load it effectively. I have looked at sqllite to understand…

Adding already works like this:
class Trie:
def __init__(self):
self.root = dict()
pass
def add(self, string, value):
global nops
current_dict = self.root
for letter in s:
nops…

I'm trying to put all words in a trie in a string, a word is detonated by the eow field being true for a certain character in the trie data structure, hence a trie can could have letters than lead up to no word, for ex "abc" is in the trie but "c"'s eow field is false so "abc" is not a word

Trying to find out if a provided Type is of a given generic type (with any generic types inside)
Let me Explain:
bool IsOfGenericType(Type baseType, Type sampleType)
{
/// ...
}
Such that:
IsOfGenericType(typeof(Dictionary<,>), typeof(Dictionary<string, int>)); // True
IsOfGenericType(typeof(IDictionary<…

I am looking to create a dictionary with 'roll-back' capabilities in python. The dictionary would start with a revision number of 0, and the revision would be bumped up only by explicit method call. I do not need to delete keys, only add and update key,value pairs, and then roll back. I will never…

I have a System.Collections.Generic.Dictionary<string, string> containing control ID and appropriate data column to data bind:
var dic = new Dictionary<string, string>
{
{ "Label1", "FooCount" },
{ "Label2", "BarCount" }
};
I use it that way:
var row = ((DataRowView)FormView1…

Like I mentioned in this post a while back, I came across a dictionary web service called Aonaware that serves up word definitions from various dictionaries and is really easy to use. The services page on their website, http://services.aonaware.com/DictService/DictService.asmx, lists all the operations…

I have a piece of code with a) which I replaced with b) purely for legibility ...
a)
if ( WORD[ INDEX ] == 'A' ) branch = BRANCH.A;
/* B through to Y */
if ( WORD[ INDEX ] == 'Z' ) branch = BRANCH.Z;
b)
switch ( WORD[ INDEX ] ) {
case 'A' : branch = BRANCH.A; break;
/* B through to Y…
