Question

/**
* Given two integers, the second larger than the first, this program:
* 1) prints the even numbers between the first and second number inclusive
* 2) prints the sum of those even numbers
* 3) prints the odd numbers between the first and second number inclusive
* 4) prints the sum of those odd numbers
*
* Example:
* Enter an integer: 10
* Enter one larger than the first: 20
* Even numbers: 10 12 14 16 18 20
* Sum of even numbers = 90
* Odd numbers: 11 13 15 17 19
* Sum of odd numbers = 75

### Implement the Pseudocode of the Preceding Problem: Reverse a String

Below is the implementation of the pseudocode for reversing a string entered by the user.

---

#### Reverse.java

```java
1 import java.util.Scanner;
2
3 public class Reverse
4 {
5 public static void main(String[] args)
6 {
7 Scanner in = new Scanner(System.in);
8
9 System.out.print("Enter a word: ");
10 String s = in.nextLine();
11 String r = "" ;
12 int i = 0;
13 while (i < s.length())
14 {
15 char c = s.charAt(i);
16 r = c + r;
17 i++;
18 }
19
20 System.out.print(r);
21 }
22 }
```

#### Testing Reverse.java

##### Test 1
- **Actual Output:**
```
Enter a word: Timed out after 5 seconds
```
- **Expected Output:**
```
Enter a word: derF
```
- **Result:**
Fail

##### Test 2
- **Actual Output:**
```
Enter a word: Timed out after 5 seconds
```
- **Expected Output:**
```
Enter a word: ippississiM
```
- **Result:**
Fail

### Explanation:

1. **Code Explanation:**
- **Lines 1-2:** Import the `Scanner` class for user input.
- **Lines 3-6:** Define the `Reverse` class and the `main` method.
- **Line 7:** Create a `Scanner` object for input.
- **Lines 9-10:** Prompt the user to enter a word and store the input in the string `s`.
- **Line 11:** Initialize an empty string `r`.
- **Line 12:** Initialize an integer `i` to 0 for indexing.
- **Lines 13-18:** Use a while loop to iterate through each character in the string `s`:
- **Line 15:** Get the character at index `i`.
- **Line 16:** Concatenate the character to the beginning of `r`.
- **Line 17:** Increment the index `i`.
- **Line 20:** Print the reversed string
