What are some clever (not ordinary) ways of implementing data structures in C, and what are some data structures that should be used more often?
For example, what is the most effective way (generating minimal overhead) to implement a directed and cyclic graph with weighted edges in C?
I know that…

When we design applications, we generally end up with the same tiered sets of data structures:
A persistent data structure that is described using DDL and implemented as RDBMS tables and columns.
A set of domain objects that consist primarily of data structures, usually combined with business-rule…

I am a newbie into the corporate world recently graduated in computers. I am a java/groovy developer. I am a quick learner and I can learn new frameworks, APIs or even programming languages within considerably short amount of time. Albeit that, I must confess that I was not so strong in data structures…

Hello,
I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call.…

There is a large stream of numbers coming in such as 5 6 7 2 3 1 2 3 .. What kind of data structure is suitable for this problem given the constraints that elements must be inserted in descending order and duplicates should be eliminated.
I am not looking for any code just ideas? I was thinking…

I have a JQGRid tree. It loads data click by click, not all at once.
Typically, JQGRid passes 4 standard tree parameters with each call - row (level, parent, is leaf, is expanded).
How can I pass more parameters that I will take from the row being expanded?
E.g. data from Name column should be passed…

I have a simple TreePanel. I would like to select a particular node upon loading it. The nodes are from a remote file (json).
The tree is loading as expected. However, the node is not being selected. Firebug shows node as undefined. This perhaps because of the async property. But, I an unable…

Hi!
I'm implementing a new machine learning algorithm in Java that extracts a prototype datastructure from a set of structured datasets (tree-structure). As im developing a generic library for that purpose, i kept my design independent from concrete data-representations like XML.
My problem now…

I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like:
java b-tree
I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets…

I am doing a project in which I require btree or b+tree data structure. Does anyone know of an existing implementation of btree or b+tree (with insert, delete, search algorithms)? It should accept string as input and form btree or b+tree of these string.
