Question
![### Programming Exercise
#### 1a) Output Analysis for Different Inputs
What is the output of the following program when the input is:
- n = 2?
- n = 4?
- n = 6?
#### 1b) Running Time Analysis
What is the running time \( T(n) \) of this program? Express the runtime in terms of Theta notation \( \Theta \) (You may assume that the input \( n \) is divisible by 2).
```java
import java.io.*;
public static void main (String args[])
{
int i, n;
java.io.DataInputStream in = new java.io.DataInputStream(System.in);
String s = in.readLine();
n = Integer.parseInt(s);
for (i = 1; i <= 1.5 * n; i++)
System.out.println("" + i);
for (i = n; i >= 1; i--)
System.out.println("" + i);
}
```
### Program Analysis
##### Output Explanation
- **For \( n = 2 \):**
The first loop runs from 1 to \( 1.5 \times 2 = 3 \), therefore it prints:
```
1
2
3
```
The second loop runs from 2 to 1, decrementing by 1 until it reaches 1, therefore it prints:
```
2
1
```
- **For \( n = 4 \):**
The first loop runs from 1 to \( 1.5 \times 4 = 6 \), therefore it prints:
```
1
2
3
4
5
6
```
The second loop runs from 4 to 1, decrementing by 1 until it reaches 1, therefore it prints:
```
4
3
2
1
```
- **For \( n = 6 \):**
The first loop runs from 1 to \( 1.5 \times 6 = 9 \), therefore it prints:
```
1
2
