Which programming language to choose for DSA and placements? (2024)

If you are a college student and you are still confused on deciding a programming language, the first thing you should do is to figure out the actual use cases for the language you choose. In this article I will help you decide in choosing a programming language based on your needs.

• C++: If your primary goal is mainly focusing in problem solving using DSA and clearing DSA rounds as part of your campus placements, C++ is the right choice as C++ is known for its speed and efficiency, making it an excellent choice for DSA. Moreover C++ has a powerful Standard Template Library (STL) that provides a wide range of data structures and algorithms making it easier to solve problems. Another big advantage is that C++ has a huge community where you can find good assistance from YouTube and other platforms to learn any specific topic. Hence most top coders choose C++ for DSA and Competitive Programming as well.
• Java: If your primary goal is not only learning DSA, but also becoming a backend developer and you don't want to waste anytime in learning a language for problem solving, then choose JAVA. Java offers a rich set of libraries for DSA, including data structures like ArrayLists, LinkedLists, and HashMaps which can make your work easier. Getting a strong hold in Java can help you in the longer run of working as a software developer in big MNCs where they still use JAVA for their backend.
• Python: If you want to become a data scientist or enter into the AI world, python is the only option. Python for DSA also is not a bad choice as python is very beginner friendly with its syntax and complexity.

If you are not clear with your goals, I suggest to blindly choose C++ and start learning the basics followed by starting problem solving. The reason is, the language you choose is not going to matter at all and all that matters is your problem solving ability. So, don't waste your time, just decide on a language and start learning it and most importantly practice daily.
