Data Structures and Algorithms courses cover organizing data with structures like arrays, linked lists, and trees, and implementing algorithms for sorting and searching. You’ll learn to analyze the performance of these methods and develop problem-solving skills through algorithmic thinking. Many courses also include coding exercises in languages such as Python or Java to reinforce these concepts.

Start with your goal. If you're focused on algorithm optimization, choose courses covering advanced data structures like graphs and trees, plus techniques such as dynamic programming and greedy algorithms. If you want to implement data structures in software development, check for courses that emphasize practical coding exercises in Python or Java and include real-world examples of how data structures are used.
