The core of computer science and technology is data structures and algorithms (DSA). Each and every aspect of computer development is dependent upon these fundamentals. Major organizations like Amazon, Facebook, and Google are searching for capable developers with excellent programming and DSA skills.
Whether you want to enhance your programming knowledge or get a better-paying job, a data structures and algorithms course is the ultimate help. However, as opposed to the common notion, you don’t need a degree or college-level education to gain these skills. These days, online courses have come of great help to students who need to upskill themselves.
The DSA concept applies to any programming language like Python or Java, so enrolling in any DSA and system design courses will be beneficial. System design courses are really important for those trying to appear for tech interviews. Most product-based companies like Microsoft and Google conduct their questions on the basis of system design concepts.
The critical thing to look out for in online courses is their course curriculum and the features they provide. You will benefit a lot from courses that provide online classes with practical applications so students learn in the best way possible.
Top data structures and algorithms online programs are mentioned below.
