Using a C# program write a program that accepts any number of homework scores ranging in value from 0 through 10. Prompt the user for a new score if they enter a value outside of the specified range. Prompt
the user for a new value if they enter an alphabetic character. Store the values in an array.
Calculate the average excluding the lowest and highest scores. Display the average as well as the
highest and lowest scores that were discarded.

The program is written using C# Console
