I'm in my third year of college and still consider myself a beginner at programming. I want to start studying data structures and algorithms seriously, but I'm unsure whether to use Java, Python, or C++. Which language would be the best choice for learning DSA and preparing for technical interviews?

C++ is a strong choice if you’re interested in competitive programming because of its speed and standard library. Java is also widely used in interviews and industry, while Python usually lets you solve problems with less code. You don’t need to master two languages immediately—choose one, build solid fundamentals, and learn another later if a target role requires it.
The language matters much less than understanding the actual concepts. Pick the one you can read and write comfortably, then focus on arrays, linked lists, trees, graphs, sorting, searching, recursion, and complexity analysis. Python is perfectly acceptable for learning and for many interviews, although you should check the requirements of the companies you plan to apply to.
I’ve heard that some companies prefer candidates who don’t use Python. Is that actually a common issue?
