Binary Search Tree (BST) A Binary Search Tree (BST) is a hierarchical data structure used for efficient searching, insertion, and deletion operations. In a binary search tree, each node contains a key value and has at most two children: a left child and a right child. The key property of a binary search tree is […]

Greedy Algorithms Greedy Algorithms are problem-solving techniques used in computer science to find optimal solutions by making locally optimal choices at each step. These algorithms aim to solve optimization problems by selecting the best available option at the current stage, without considering the consequences of that choice in the future. The key features of greedy

Divide and Conquer Algorithm Divide and Conquer is a fundamental algorithmic paradigm used to solve problems by breaking them down into smaller subproblems, solving the subproblems independently, and then combining their solutions to obtain the final solution. The Divide and Conquer approach typically involves three steps: Divide: Break the problem into smaller, more manageable subproblems

A Complete Guide to Dynamic Programming Dynamic Programming is a problem-solving technique based on the principle of overlapping subproblems and optimal substructure. The fundamental idea behind dynamic programming is to solve each subproblem only once and store its solution, avoiding redundant computations. This approach leads to significant efficiency gains, especially for problems with overlapping subproblems,

Recurrence Relation in Algorithm A Recurrence Relation is a mathematical equation that defines a sequence recursively, where each term is defined in terms of preceding terms. It typically consists of two parts: an initial condition or base case that specifies the first few terms of the sequence, and a recurrence relation that describes how subsequent

Pseudocode Conventions Pseudocode is a high-level description of an algorithm that uses natural language mixed with some programming language-like constructs. It provides a step-by-step outline of the algorithm’s logic without being tied to any specific programming language syntax. Pseudocode allows algorithm designers to express their ideas in a concise and understandable manner before actual coding

Asymptotic Notations and its Applications Asymptotic Notations is a mathematical framework used to describe the behavior of functions as their input values approach certain limits. In the context of algorithm analysis, it helps us understand how the performance of an algorithm scales with the size of its input. Three common forms of asymptotic notation are:

Analysis of Algorithms Algorithm analysis is the process of evaluating the performance and efficiency of an algorithm. It involves studying the resource usage (such as time and space) of an algorithm and predicting how it will behave as the input size grows. The primary goals of algorithm analysis are to: Determine the running time of

Complexity of an Algorithms Algorithmic complexity refers to the efficiency of an algorithm concerning the amount of time and space it requires to solve a problem. It’s a crucial aspect of algorithm design, as it directly impacts the performance of software systems, especially when dealing with large datasets or resource-constrained environments. Algorithmic complexity is often

Introduction to Algorithms Algorithms are step-by-step procedures or sets of rules used for solving a specific problem or performing a task. They are the fundamental building blocks of computer programs and play a crucial role in various fields, including computer science, mathematics, and engineering. Algorithms define a sequence of operations that transform input data into
