Data structures and Algorithms Course - Learn & Master DSA Online

What are Data Structures?

Data Structures are typically used to organize, process, retrieve and store data on computers for efficient use. Having the right understanding and using the right data structures helps software engineers write the right code.

What are the types of Data Structures?

There are two types of Data structures -

  • Linear Data structure: If the elements of a data structure result in a sequence or a linear list then it is called a Linear data structure. Every data element is connected to its next and sometimes previous element in a sequential manner. Example - Arrays, Linked Lists, Stacks, Queues, etc.
  • Non-linear Data structure: If the elements of a Data structure result in a way that the traversal of nodes is not done in a sequential manner, then it is a Non-linear data structure. Its elements are not sequentially connected, and every element can attach to another element in multiple ways. Example - Hierarchical data structure like trees.

    • Why are Data Structures important?

    Data structures are a key component of Computer Science and help in understanding the nature of a given problem at a deeper level. They're widely utilized in Artificial Intelligence, operating systems, graphics, and other fields. If the programmer is unfamiliar with data structure and Algorithm, they may be unable to write efficient data-handling code.

  • A strong grasp of this is of paramount significance if you want to learn how to organize and assemble data and solve real-life problems
  • Almost all product-based companies look at how strong you are at data structures, so it will also help you in your day-to-day work
  • Knowing when to apply the proper data structures is an important step to write efficient code by managing data properly

    I am happy to share that I have joined ThoughtWorks as an Application Developer. After experiencing a couple of failed & awkward interviews, I realized I needed to work on my skills in order to crack them. From building the foundations of DSA to simplifying the concepts of System Design, the program delivered EXACTLY what it said. Even the teachers and TAs tackled each problem in an easy and well-defined structure. The curriculum here is well thought out which added discipline to my routine. It was only after I joined Scaler Academy I received offers from multiple companies, that honestly felt unreal. Thanks to Scaler for creating this platform and a big shoutout to my mentors who not only guided me but also made a proper roadmap for me to be able to achieve success in interviews. I would also like to thank the recruitment team for their help and support.

I am grateful to the founders of Scaler Academy for creating such a wonderful learning platform. I feel blessed to have the finest instructors & mentors. I am extremely glad to have gotten constant support from my mentor who has helped me through the interview process, thank you Scaler for introducing me to a big brother. Lastly, would like to thank the recruitment team for bringing in so many interview opportunities.

    I am extremely thrilled that I will be joining Lendingkart as a Software Engineer. Grateful to Scaler Academy for helping me improve my problem-solving skills and making me understand DSA in a simpler way. Trees, Graphs related problems have always been a nightmare for me. Never imagined solving such problems with ease, thus, would like to thank the Scaler team for their tremendous support. Much thanks to the recruitment team who helped me through the recruitment related process. Thank you everyone from Scaler for all the support and guidance.

    I am pleased to share that I have joined WorkSpan as a Software Engineer. For this, I would like to thank Scaler Academy for teaching me how to think rather than only showing me the ways to solve a problem. Thanks to the Scaler team for teaching how large-scale systems are built. Other than that, thanks to all the instructors for teaching structures & algorithms, backend development and for teaching me recursion, concurrency, and Redis. This program has also made me strong in computer fundamentals (CN, DBMS & OS). Lastly, I would like to thank the recruiter team for arranging interviews with the companies.

    As a software engineer/programmer, one should understand the core concepts of data handling. Understanding data structures and algorithms will benefit candidates in coding interviews, as they will be able to write efficient code to handle the data presented by the interviewer/interviewers. They can write code in any programming language with minimal effort

    Product companies worldwide screen applicants based on their grasp of data structures and algorithms. Aside from getting through to product-based companies, the application of data structures and algorithms in the tech world is huge. DSA has been the core of computer programming from the beginning and has been the building block of the software development process, it is incorporated into all of the important languages. The efficiency of software development depends on the choice of an appropriate data structure and algorithm

    There are a number of coding languages with data structures. Among them, C++ and Java stand out for their ease in using DSA. Python, Javascript are some other notable languages to learn data structures

    The key to mastering DSA is to practice as many problems as possible and do so consistently. We provide a pool of problems focused on data structures and algorithms to help you practice as much as you want, stay consistent, and track your progress. Establishing a solid foundation is crucial so staying patient and continuing the pace of learning will eventually pay off

    Data Structures and Algorithms module, which is covered under the Scaler Academy Program will give you expert-level knowledge of DSA and prepare you for interviews that will help advance your career. Students will receive advanced and valuable training in data structures, algorithms, and large-scale systems design, as well as gain insight into how various DSAs work. Recursion, arrays, linked lists, stacks, queues, strings, binary search, trees, heaps, arithmetic operators, loops, etc., will also be covered by experienced instructors.

    Enrolling in the Scaler Academy program, which covers Data Structures and Algorithms will prepare you for interviews and help you advance your career. You'll gain extensive practical experience by working on real-world projects. Students are provided with a well-structured curriculum curated by industry experts that combines CS basics, web development skills, and fundamental DSA skills that will prepare them for technical interviews. Besides improving fundamental DSA skills, our instructors and mentors are well-equipped to assist candidates with behavioral interviews.

    No, learning Data Structures and Algorithms is not difficult as long as you have the motivation to learn. Developing this skill or knowledge simply requires practice and time. Once you've learned the fundamentals of data science, learning algorithms is a great next step.
