DATA STRUCTURE AND ALGORITHMS
What is data structure and algorithms ?
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.
The algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. Algorithms are generally created independent of underlying languages, i.e. an algorithm can be implemented in more than one programming language.
From the data structure point of view, the following are some important categories of algorithms −
- Search − Algorithm to search an item in a data structure.
- Sort − Algorithm to sort items in a certain order.
- Insert − Algorithm to insert an item in a data structure.
- Update − Algorithm to update an existing item in a data structure.
- Delete − Algorithm to delete an existing item from a data structure.
why to learn data structure and algorithms
With advancement and innovation in technology, programming is becoming a highly in-demand skill for Software Developers. Everything you see around yourself from Smart TVs, ACs, Lights, Traffic Signals uses some kind of programming for executing user commands.
Programs are comprised of two things: data and algorithms. The algorithms describe the way the data is to be transformed. The reason for learning about data structures is because adding structure to our data can make the algorithms much simpler, easier to maintain, and often faster.
Data structure helps to build the algorithm in a much easy way. It gives a structure to the much increases one’s efficiency of coding up to 90%. It is the main pillar of programming.
Uses of data structure and algorithm
Data structures serve as the basis for abstract data types (ADT). Data structures provide a means to manage large amounts of data efficiently for uses such as large databases and internet indexing services. Usually, efficient data structures are key to designing efficient algorithms.
Online or offline preparation
Online or Offline preparatory is totally depends upon the comfort of the student. online study is specially meant for the students who are having a phobia of thick books. All the written notes and video lectures are available on youtube and over different platforms with various teachers. Moreover, the subject is also added in the GATE examination. so one who wants to crack the examination must study it the more appropriate way. Tip: While the subject is included in the semester one should go through each and every topic carefully and also cover the previous question papers and question banks for preparing more deeply and one should be comfortable in the future while preparation for cracking the GATE examination!!
