✅ Data structures and algorithms are two essential concepts in computer science and programming.

✅ Data structures refer to the way we organize and store data in a computer program. They are used to manage and manipulate data efficiently. Some common data structures include arrays, linked lists, stacks, queues, trees, and graphs.

✅ Algorithms, on the other hand, are a set of steps or instructions that are followed to solve a problem. Algorithms can range from simple to complex, depending on the problem being solved. Some common algorithms include searching, sorting, and traversal algorithms.

✅ By choosing the right data structure and algorithm, programmers can write efficient and effective code that solves complex problems.
