Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

Question

When looking at this code making recursive calls, how would I identify how many recursive calls are being made?

### Recursive Method Analysis

#### Problem Statement:
How many recursive calls does the following method contain?

#### Method Definition:
```java
public static int multiplyEvens(int n)
{
if (n == 1) {
return 2;
} else {
return 2 * n * multiplyEvens(n - 1);
}
}
```

#### Answer Options:
- ☐ 0
- ☐ 2
- ☑ 2*n
- ☐ 1

### Explanation:
The method `multiplyEvens` is a recursive function designed to compute the product of the first `n` even numbers. The function continues to make a recursive call with the parameter `n-1` until it reaches the base case where `n == 1`.

For `n = 1`, the function directly returns 2 without further recursive calls. However, for any `n > 1`, the function calls itself with a decremented value of `n`, thus the total number of recursive calls depends linearly on `n`.

The correct response indicating the number of recursive calls is `2*n`, which corresponds to the recursive depth of the function's execution path.
