Write a program that has two command line arguments. One argument describes a filename and the other is related to the verbosity of the application.

1. Argument -f is required and it is used to give a filename for the application. It needs a value.

If this argument isn't present, print out No file specified! (use the -f argument) and stop the execution of the application

2. Argument -v is optional and it has no value

If -v argument is not given, the program prints the full value of the - f argument

If the -v argument is given, the program prints out the value of the - f argument without the file extension

3. The arguments can be given in any order.

4. Examples

dotnet run -- -f file.txt -v prints file

dotnet run -- -f file.txt prints file.txt

dotnet run -- -v -f file.txt prints file

5. Misc

You can assume the filename is always in the format . so there's no need to check if that's the case.
