Implement extension functions plus and minus to perform vector addition and subtraction.
Task Description:
- data class Vectoris given with a propertycoordinates, a list of integers representing the vector’s coordinates.
- Implement a function plusfor theVectorclass to add two vectors. The function should return a newVectorrepresenting the sum.
- Implement a function minusfor theVectorclass to subtract two vectors. The function should return a newVectorrepresenting the difference.
- Ensure both functions handle cases where vectors have different dimensions by returning nullor an appropriate error message.
- Make operator invocations possible:
Example usage:
Vector(listOf(1, 2, 3)) + Vector(listOf(4, 5, 6)) == Vector(listOf(5,7,9)
Vector(listOf(-1, -3)) - Vector(listOf(-2, -2)) == Vector(listOf(1, -1))
Vector(listOf(3, 4, 5)) - Vector(listOf(1, 2)) == null- Fill in the code.
- You can copy the code into IntelliJ/Android Studio, but it shouldn’t be necessary.
- Click “run” – the green triangle. The code will compile and several tests will be run.
- In the logs, you will see “try again” if the solution is incorrect, or “success” and a special code.
- Provide this code in the form below along with your email and click “send”.
