Transcribed Image Text:### Understanding Recursion in Code
#### Problem Statement:
What type of recursion is present in the method below?
#### Code Explanation:
```java
public static void mystery(int x, int y) {
if (x <= 0) {
System.out.print("cat");
} else if (y < 2) {
System.out.print("bat");
mystery(x-1, y);
} else {
System.out.print("mat");
mystery(x-1, y-2);
}
}
mystery(4, 5);
```
#### Recursion Type Options:
- ○ mutual
- ○ linear
- ○ nested
- ○ tree
- ○ tail
### Detailed Analysis:
The `mystery` function uses three different print statements based on the values of `x` and `y`. It recursively calls itself with modified arguments:
- Decreases `x` and calls `mystery` if `x > 0`.
- Decreases `y` by 2 in some cases.
This pattern leads to multiple recursive calls potentially branching out, which characterizes **tree recursion**. Each call may lead to further calls, forming a tree-like structure.
