# Explain the concept of recursion and how it is used in algorithm design.

[Explain](https://www.mindstick.com/forum/157854/what-is-system-debugging-explain-some-system-debugging-tools-used-in-modern-computer-systems) the [concept of recursion](https://www.mindstick.com/forum/158955/explain-the-concept-of-recursion-in-python-and-provide-an-example) and how it is used in [algorithm design](https://www.mindstick.com/forum/159503/when-might-encounter-an-exception-related-to-a-divide-by-zero-error-in-algorithm-design).

[Recursion](https://answers.mindstick.com/qa/111681/what-is-recursion-and-when-should-i-use-it) is a programming technique that involves calling a function within itself. In other words, a function can call itself repeatedly until a certain condition is met.

In [algorithm](https://www.mindstick.com/blog/119/implementing-cryptography-in-c-sharp-dot-net-by-using-sha1-algorithm) design, recursion is often used to solve problems that can be broken down into smaller subproblems. The idea is to solve the larger problem by solving the smaller subproblems recursively.

A recursive function typically has two parts: the base case and the recursive case. The base case is the stopping condition that determines when the function should stop calling itself and return a result. The recursive case is the part of the function that calls itself again with a smaller subproblem.

Here is an example of a recursive function to compute the factorial of a number:

```java
public int factorial(int n) {
   if (n == 0) {
       return 1; // base case
   } else {
       return n * factorial(n - 1); // recursive case
   }
}
```
