Recursion

Recursion is a programming technique where a function calls itself to solve a problem by breaking it down into smaller subproblems. It is commonly used in algorithms and data structures, such as tree traversal, sorting, and search algorithms, to simplify complex problems and reduce code duplication. Readers can learn how recursion works, its advantages and limitations, and how to implement recursive algorithms in programming languages like Python, Java, and JavaScript, improving problem-solving skills and understanding of algorithmic concepts.
