In computer science, big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size grows.[3] In analytic number theory, big O notation is often used to express a bound on the difference between an arithmetical function and a better...

Circular linked list is a linked list where all nodes are connected to form a circle. There is no NULL at the end. A circular linked list can be a singly circular linked list or doubly circular linked list. Circular Linked List #1 Test 1 In a conventional linked list,...

Take a look at full implementation of Stack Stack was implemented according to the principle: LIFO = FILO Pile of books. If we want to retrieve a book from this stack, you can take the book on top. Taking a book from the bottom is a bit precarious and we...

Take a look at full implementation of DFS. Depth-First Search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible...

Recursion…A recursive function occurs when a function that calls itself until a “base condition” is true, and execution stops. Everyone knows it, no one uses it. I’m just kidding. Writing this post I was trying to remind myself when it was the last time I used it. Two scenarios come...

The first thing to understand is that a string in Python or C ++ is a variable length array. This seemingly small difference is quite important from a systemic point of view: a normal array is statically determined in the program from the start has a known length we know...

We can distinguished three different types of linked lists: Singly Linked Lists Doubly Linked Lists Circular Linked List Take a look at full implementation of Linked List. A linked list is a data structure that represents a list of items, just like an array. In fact, in any application in...

The array is one of the most basic data structures in computer science. We assume that you have worked with arrays before, so you are aware that an array is simply a list of data elements. The array is versatile, and can serve as a useful tool in many different...
