DSA Tutorial - Learn Data Structures and Algorithms

Greedy Algorithm builds up the solution one piece at a time and chooses the next piece which gives the most obvious and immediate benefit i.e., which is the most optimal choice at that moment. So the problems where choosing locally optimal also leads to the global solutions are best fit for Greedy. Greedy Algorithms Guide; Quiz on Greedy; 21.

What is an Algorithm? - Introduction, Types & Examples - Intellipaat

Dynamic programming algorithms are used to solve problems that can be broken down into smaller sub-problems. They use a bottom-up approach, starting with the simplest sub-problems and building up to the more complex ones. This approach is used to find the optimal solution to a problem by avoiding redundant calculations.

Data Structures and Algorithms: A Detailed Guide - The Knowledge Academy

Algorithms, in contrast, are step-by-step instructions for solving a particular problem. They define the logic and operations required to manipulate and process data stored in Data Structures. Efficient Algorithms are vital for optimising resource usage and improving the execution time of programs. Let's explore an example of Algorithm:

Computer science - Algorithms, Complexity, Programming | Britannica

An algorithm is a specific procedure for solving a well-defined computational problem. The development and analysis of algorithms is fundamental to all aspects of computer science: artificial intelligence, databases, graphics, networking, operating systems, security, and so on. Algorithm development is more than just programming. It requires an understanding of the alternatives available for ...
