Programming has always been a high-demand profession for software developers, and it is much more so now, thanks to technological advancements. The ultimate foundation of programming is data structures and algorithms. They are quite beneficial in resolving difficult situations in the real world. That’s why, when interviewing for technical positions, digital giants like Google, Facebook, Microsoft, Amazon, and other product-based organizations focus on testing a candidate’s mastery of algorithms and data structures. Data structures and algorithms are essential for becoming a skilled programmer since they considerably increase one’s problem-solving capabilities.
Furthermore, with all of the excitement around data science and machine learning, many students and professionals are launching their careers in these sectors on a daily basis. Learning algorithms and data structures is critical for these individuals, especially if they do not have a background in computer science.
Taking an online course is the greatest approach to understand data structures and algorithms. These days, there are a plethora of internet tools that may assist you in taking your expertise to the next level. It also allows you to work at your own speed and devote more attention to areas that you find difficult to grasp. This is a list of the greatest online data structures and algorithms courses, classes, tutorials, and certification programs. These include both free and paid university-level courses provided by prominent colleges, as well as programs provided by industry experts.

2. Python for Data Structures, Algorithms, and Interviews!
Jose Portilla, who has taught thousands of students about Python programming and Data Science, is offering this Udemy data structures and algorithms course. He built this course to assist students with the coding interview process at some of the world’s most prestigious technology firms. It’s a three-in-one course that covers Python data structures and algorithms, technical coding interview questions and solutions, and non-technical interview preparation such as resume evaluations and in-person interview preparation. The course costs $118 and you can sign up for it using the below-provided link.
3. Data Structures and Algorithms: Deep Dive Using Java
This Java data structures and algorithms course by Tim Buchalka and his colleagues is one of the finest on Udemy. It focuses on the implementations of data structures and algorithms rather than mere theory to provide students a thorough grasp of how things function. This course is different in that it spends a lot more time looking at what’s accessible in the JDK, so students can better grasp how things function beneath the hood and apply what they’ve learned to their own future programming projects. The course costs $88 and you can sign up for it using the below-provided link.
4. Mastering Data Structures & Algorithms using C and C++
This is the most thorough and immersive course on data structures and algorithms in C and C++, with over 56 hours of video sessions. It concentrates on three elements of data structure learning: comprehending the theory and ideas, analyzing data structures and performing various operations on them, and creating data structures in C and C++. The course costs $118 and you can sign up for it using the below-provided link.
5. Master the Coding Interview: Data Structures + Algorithms
This is the most popular and finest coding interview course on Udemy for programmers and developers. It covers the fundamentals of computer science, giving students a significant advantage in interviews. The purpose of this course is to advance participants’ programming abilities by teaching the concepts and core ideas, as well as conducting exercises and problems step by step so that they grasp why and how things function beneath the hood. The course costs $118 and you can sign up for it using the below-provided link.
6. Practical Data Structures & Algorithms in Java + HW
This course will cover data structures including lists, stacks, queues, and trees, as well as some of the most sophisticated sorting, searching, and graph algorithms that have revolutionized computing. I keep things practical throughout the course, providing real-world examples of how all of these algorithms function and when and when they may be used to develop efficient computer programs. The course costs $118 and you can sign up for it using the below-provided link.
7. Introduction to Data Structures & Algorithms in Java
This course includes basic data structures and algorithms (arrays, linked lists, stacks, queues, trees, and heaps) (various sorting algorithms, and algorithms for operations on binary search trees and heaps). This course will also address recursion. The lessons are very simple to understand because of the use of pictures and animations. You will lose your phobia of data structures and algorithms after completing this course. The course costs $57 and you can sign up for it using the below-provided link.
8. Master the Coding Interview: Big Tech (FAANG) Interviews
The course’s purpose isn’t to encourage you to “do 100 interview questions and remember their answers.” Certainly not! The course’s objective is to provide you with a framework to answer ANY interview question that these firms may throw at you, using the hand-picked typical interview questions. Rather than trying to remember frequent questions, we teach you the ideas and basics that you can use to spot common patterns in questions so that you can answer any question with confidence in your programming interview. The course costs $118 and you can sign up for it using the below-provided link.
10. Data Structures in Java – Part I (+INTERVIEW QUESTIONS)
Data structures and algorithms are the focus of this course. The issues will be implemented in Java. The course will take you about 14 hours to finish. To obtain a clear understanding of these data structures, it is highly advised that you type them out on your own multiple times. The course costs $118 and you can sign up for it using the below-provided link.
