How to Learn Algorithms And Data Structures

YASH PAL,

Guide on How to Learn Algorithms and Data Structures – If you want to learn algorithms and data structures to build your skills. then you are in the right place. to fully understand how to learn algorithms and data structures full read this post. Then, you can decide whether this is right for you or not. 

And if you find that this post is right for you then please click on any advertisement shown on this page. it really helps me. so let’s start the topic…

How to learn Algorithm?

If you are a technical person, you should be familiar with algorithms. and if you don’t know, then I will tell you.

The algorithm is a way to solve the problem. and used for creating logic and getting the best and simplest solution to the problem. and used to find an effective method for a problem. and it has a starting point and an ending point. 

Now the technology is becoming widespread. and every day we face new problems in the technical field. so the algorithm is the best way to solve any problem and get the idea of how a problem is solved. and now time this thing is essential and recommended.

“so there are the lists of topics which you should learn in algorithms for solving any type of technical problem.”

first of all, you need to know what algorithms are and why we use this topic to solve the problem. then you should get started in the field of algorithms. below is given step-by-step process to learn the algorithm. Follow and learn all these topics, and you will be a master in algorithms and data structures.

First step

  1. How to sort an algorithm
  2. Should learn how to analyse and design an algorithm

Second step

  1. What is big O notation
  2. Big O notation examples
  3. What is Asymptotic notation
  4. What is Standard notation

Third step

  1. The indicator of random variables and random algorithm
  2. The hiring problem
  3. Probabilistic analysis

Fourth step

  1. Bellman-Ford algorithm
  2. Multithreaded algorithms
  3. Dijkstra’s algorithm
  4. The simplex algorithm
  5. Relabel-to-front algorithm

  7. Floyd-Warshall algorithm
  8. Kruskal and Prim algorithm
  9. Push-relabel algorithm
  10. Knuth-Morris-Pratt algorithm
  11. Strassen’s algorithms

For a better understanding of the algorithm and for practice. you can solve these problems. like Rotations, insertion, deletion, matrix multiplications, recursion, hiring problem, and you should be used algorithms to solve the data structure problems. like how to create a linked list. 

And how to create stacks and queues. how to represent trees and create binary trees. problems for Hashtables, for creating Heaps.

How to learn Data Structures?

Further learning Data Structures you have at least knowledge of one programming language. so you can easily and fully understand this topic.

Data structure uses to arrange to data. because in now time the production of data on the internet grow up rapidly. and all the data is in unstructured form.
