Based on the inspiration from the accompanying example, you are in this exercise supposed to experiment with some simple C# arrays.
First, consult the documentation of the class System.Array. Please notice the properties and methods that are available on arrays in C#.
Declare, initialize, and print an array of names (e.g. array of strings) of all members of your group.
Sort the array, and search for a given name using System.Array.BinarySearch method.
Reverse the array, and make sure that the reversing works.
