Question
Compute the distance between the positions of the first and last zero element in the given array. For example if the array is 3 0 1 0 4 9 5 0 6 your algorithm should yield 7 - 1 = 6. If the array contains a single zero return 0. If it doesn’t contain any zeros return a negative value

![### Java Code Snippet for Educational Purposes
#### Overview
This image displays a Java integrated development environment (IDE) with a code snippet from a file named `Numbers.java`. The code defines a public class `Numbers` with a static method `zeroesDistance`.
#### Code Explanation
```java
public class Numbers {
public static int zeroesDistance(double[] values) {
int firstPos = 0;
int lastPos = values.length - 1;
boolean found = false;
while (firstPos < values.length && !found) {
/* Your code goes here */
}
return lastPos - firstPos;
}
}
```
- **Class Declaration**: `Numbers` – This is the name of the class.
- **Method Declaration**: `zeroesDistance` – A static method that accepts an array of doubles and returns an integer.
- **Variables**:
- `firstPos`: Initialized to 0, likely used to track the initial position.
- `lastPos`: Initialized to the last index of the `values` array.
- `found`: A boolean set to `false`, potentially for controlling the loop.
- **While Loop**: Contains a placeholder for the code, indicated by the comment `/* Your code goes here */`. This loop appears to iterate through the `values` array until a condition is met.
- **Return Statement**: Returns the difference between `lastPos` and `firstPos`.
#### Projects and Files
The left pane shows a file explorer with several Java files listed, indicating additional projects that might relate to different coding exercises or demonstrations.
#### Console Output
At the bottom, there's a console output showing interaction with a program, likely related to the code:
- Input Series: "Enter scores, -1 to quit"
- Output Series: The scores entered are displayed, indicating a user input and echoing sequence.
- **Process Completion**: The process finished successfully with exit code 0.
