Recurrence Relation

Recurrence relation is an equation that expresses the nth term of a sequence as a function of k preceding terms, for some fixed k (independent from n), which is called the order of the relation. Once k initial terms of a sequence are given, the recurrence relation allows computing recursively all the remaining terms of the sequence.

Asymptotic analysis in practice

So far we have seen that what Asymptotic analysis is. In this article we'll explore the uses of Asymptotic analysis.

Asymptotic analysis

The asymptotic analysis defines the mathematical foundation of an algorithm's run time performance. If there is no input to an algorithm then the algorithm will always work at a constant time. Asymptotic analysis is the running time of any process or algorithm in mathematical terms.

Analysis of the Algorithm

The analysis of algorithms is the process of finding the computational complexity of algorithms—the amount of time, storage, or other resources needed to execute them.

What is the analysis of the Algorithm?

The analysis of algorithms is the process of finding the computational complexity of algorithms—the amount of time, storage, or other resources needed to execute them. Usually, this involves determining a function that relates the size of an algorithm's input to the number of steps it takes (its time complexity) or the number of storage locations it uses (its space complexity).

Introduction to Algorithm and Data Structure

A data structure is a named location that can be used to store and organize data. And, an algorithm is a collection of steps to solve a particular problem. Learning data structures and algorithms allow us to write efficient and optimized computer programs

What is Data structure?

In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, i.e., it is an algebraic structure about data.

What is the Algorithm?

A method or set of instructions that must be followed when performing problem-solving operations. As a result, an algorithm is a collection of instructions that govern how a work is to be conducted step-by-step to achieve the desired result termed as an algorithm.
