It is observed that the world of computer science works hand-in-hand with data structuring and algorithms. They are the baseplate for all the other parts of computer science and development. This is another reason why titans such as Google, Microsoft, and Facebook are looking specifically for programmers who are wizards with data structures and algorithms. Therefore, learning DSA is highly beneficial to a person whether they seek a job or try to improve their skills. One needn’t spend a boatload of money on a college education to learn how to code. This is where Online Courses come into play. They are a massive learning source and count as proof of skill during interviews. Below are a few examples of the best Online Data Structures and Algorithm courses. They are:
Scaler Academy’s Data Structure and Algorithm Course:
Scaler Academy’s course has a particular way of explaining the most challenging topics in DSA that anyone can easily comprehend. These courses are available for all levels- Beginners, Intermediates, and Advanced. If these three presets are too slow or too fast for you, then the curriculum can be optimised to match your pace of learning. Projects and assignments at the end of a lesson will help instil the concepts one has learned permanently. This course covers the following:-
- The basics of programming
- Time Complexity
- Arrays
- Strings
- Binary Search
- 2 Pointers, Recursion

Duration: 10.126 months.
Eligibility: Graduates from 2021 and before can apply.
Price: 2.5 lakhs, the monthly price comes down to 7,200 Rs with either scholarships or EMI.
Algorithms and Data Structures- Part 1 and 2 (Coursera)
This more advanced course covers the basics of algorithms and data structures that every severe programmer must know, primarily focusing on Java implementations and scientific performance analysis. Topics such as Basic data structures, sorting, and searching strategies are covered in the first section of this course. The second part of this course is exclusively designed to explain and help understand graph and string processing techniques. This course includes all these features for free; it also comes with a certificate of completion, which you must pay for. Amongst the many topics taught in this course, a few are:-
- Union-find
- Analysis of algorithms
- Stacks and queues
- Elementary sorts
- Merge sort
- Quicksort
- Priority queues
- Elementary symbol tables
- Balanced search trees
- Geometric applications of BSTs
- Hash Tables
- Symbol table application
Duration: approximately 53 hours; goals can be set according to each person’s schedule.
Level: Intermediate.
Price: Free of cost.
Data Structures- University of California San Diego
The standard data structures that are used to solve many computer-related problems are discussed in this online course. You learn how to implement data structures in many different programming languages. This will help you understand what is happening in a particular built-in data structure implementation and what to expect. Within this course, you shall learn:-
- Basic Data structures
- Dynamic arrays and amortised analysis
- Priority queues and disjoint sets
- Hash tables
- Binary search trees
Duration: approximately 25 hours.
Level: Intermediate.
Price: Free of cost.
