Arrays and Strings are the foundation of many Data Structures and Algorithms problems. This section focuses on basic operations such as traversing arrays, finding maximum or minimum values, counting elements, reversing data, searching, and handling characters in strings. These problems help you build strong problem-solving skills before moving to advanced patterns. You will also learn how to think about time and space complexity while solving simple problems. Mastering these basics makes it much easier to understand more advanced DSA concepts.
