Introduction An array is a contiguous block of memory of the same type of elements where the size is equal to the number of elements in that…

What is a Heap? A heap is a complete binary tree structure where each element satisfies a heap property. In a complete binary tree, all…

Why do we study the design, code, and analysis of the sorting algorithms? Here are some critical reasons: We can learn several problem…

Why should we learn data structures? The code of a well-designed algorithm using data structure is just like a structure of a good house…

Millions of users on the internet are generating terabytes of content every day, and the amazing part is: the amount of content is doubling…

Introduction to tree traversal To process data stored in the tree data structure, we need to traverse each node of the tree. The process to…

Introduction to iterative tree traversals In all recursive DFS traversals of a binary tree, we have three basic elements to traverse— root…

Introduction to level order traversal In the DFS traversal of a binary tree, we access nodes in three different orders — preorder, postorder…

Why analysis of algorithms is important? Deciding the efficient algorithm among more than one algorithms. Estimating algorithm performance…

Recursion is one of the popular problem-solving approaches in data structure and algorithms. Even some problem-solving approaches are…

Loop is a fundamental problem-solving operation in programming. A lot of coding problem solutions involve various kinds of loop structures…

Input: An array X[] of n integers Output: A permutation (reordering) of input such that X[0] <= X[1] <= X[2] .... <= X[n-2] <= X[n-…

What is iteration in programming? To solve a problem, sometimes it is necessary to repeat a particular code statement several times…

Most programmers need to realize the importance of data structure and algorithms as early as possible in their careers. The reason would be…

Before the invention of computers, there were algorithms. Now computers are everywhere, so algorithms are everywhere! Algorithms lie at the…

Recursion means “solving the problem via the solution of the smaller version of the same problem” or “defining a problem in terms of itself…

Algorithmic Thinking has recently become a buzzword among programmers. It is a method for solving problems based on a clear definition of…
