Write a C# console program that asks the user how many grades there are, inputs the grades, and displays the median of those grades.

Your program must:

1. Store the grades in an array.

2. Handle up to 20 grades

3. Sorts the array of grades.

4. Have a method that takes a sorted array of grades. It returns the median of those grades.

5. Use at least one reference or output parameter

Sample Output

Please enter the number of grades: 6

Please enter grade #1: 85.2

Please enter grade #2: 92.3

Please enter grade #3: 78.0

Please enter grade #4: 51.5

Please enter grade #5: 91.6

Please enter grade #6: 87.0

The median grade is 86.1
