Recursion

Recursion is a method in mathematics and computer science where a function, process, or definition refers to itself directly or indirectly. It is commonly used to solve problems by breaking them down into simpler, smaller instances of the same problem. Recursive algorithms typically include a base case to terminate the process and prevent infinite loops. Recursion is fundamental in areas such as algorithm design, data structures (like trees), and mathematical sequences. Its use enables elegant solutions to complex problems but requires careful handling to ensure efficiency and correctness.
