A data structure is a way of organizing data in a fashion that allows particular properties of that data to be queried and/or updated efficiently.
I've seen people say that set objects in python have O(1) membership-checking. How are they implemented i
I've been learning about different algorithms in my spare time recently, and one that I came across which
As I was programming, I haven't seen an instance where an array is better for storing information than an
Why is std::map implemented as a red-black tree? There are several balanced binary search trees (BSTs) out th
Why would someone want to use a linked-list over an array? Coding a linked-list is, no doubt, a bit more work
I have a data structure which essentially amounts to a nested dictionary. Let's say it looks like this:
In Python, which data structure is more efficient/speedy? Assuming that order is not important to me and I wou
I know a map is a data structure that maps keys to values. Isn't a dictionary the same? What is the diffe
I recently came across the data structure known as a skip list. It seems to have very similar behavior to a bi
I was looking for a tree or graph data structure in C# but I guess there isn't one provided. An Extensive
I am trying to construct a General tree. Are there any built-in data structures in Python to implement it?
Python includes the heapq module for min-heaps, but I need a max heap. What should I use for a max-heap imple
I'm interested: What is C#'s analog of std::pair in C++? I found System.Web.UI.Pair class, but I&apo
In a b-tree you can store both keys and data in the internal and leaf nodes, but in a b+ tree you have to stor
When should I use a dictionary, list or set? Are there scenarios that are more suited for each data type?
I'm trying to answer two questions in a definitive list: What are the underlying data structures used fo
Brief background: Many (most?) contemporary programming languages in widespread use have at least a handful of
This is a simple question from algorithms theory. The difference between them is that in one case you count nu
Can anyone please explain the difference between binary tree and binary search tree with an example?
