Defined below is a simple main method that calls upon surprise(int a, int b, int c), a recursive method that takes three ints as its parameters. Fill in the parameters of the third recursive call made by the surprise() function. Do not include surprise(4, 8, 3) in your count. Start with the next call to method surprise. public static void main(String[] args) { System.out.println(surprise(4, 8, 3)); } public static int surprise(int a, int b, int c) { if (a == 0) { return c; } } if (a % 2 == 0) { return c + surprise (a-1, b+1, c); } return c + surprise (a-1, b, c+1); surprise(

### Recursive Method Example

The following code snippet demonstrates a simple main method that calls a recursive function `surprise(int a, int b, int c)`. This function takes three integers as its parameters. The task is to identify the parameters of the third recursive call made by this function, excluding the initial call `surprise(4, 8, 3)`.

```java
public static void main(String[] args) {
    System.out.println(surprise(4, 8, 3));
}

public static int surprise(int a, int b, int c) {
    if (a == 0) {
        return c;
    }
    if (a % 2 == 0) {
        return c + surprise(a-1, b+1, c);
    }
    return c + surprise(a-1, b, c+1);
}
```

**Explanation of Code Logic:**

1. **Base Case:** If `a` is 0, the function returns `c`.
2. **Even `a`:** If `a` is even, the function calls itself with parameters `(a-1, b+1, c)`.
3. **Odd `a`:** If `a` is odd, the function calls itself with parameters `(a-1, b, c+1)`.

### Task

After the initial call with parameters `(4, 8, 3)`, determine the parameters of the third recursive call:

```plaintext
surprise( , , )
```

By analyzing the flow of recursive calls:
1. **First call:** `surprise(4, 8, 3)` leads to `surprise(3, 8, 4)`.
2. **Second call:** `surprise(3, 8, 4)` leads to `surprise(2, 8, 5)`.
3. **Third call:** The next call is `surprise(2, 8, 5)`, which would follow the path for `surprise(1, 9, 5)`.

Thus, the parameters for the third recursive call are:

```plaintext
surprise(1, 9, 5)
```
