Data structure and Algorithms (DSA) are independent of any programming language that you use, but if you prefer to learn that by using Oops you may try C++ or Java or other languages that support Oops (ex. Python). In between C++ and Java, Java is convenient for a beginner as you can focus on the concept of Oops and DSA, by forgetting about the complexities of memory deallocation and smart pointers. But if you like to play more on core concepts you will enjoy learning DSA with C++.

I'm available if you need help with this.

All the best!!
