Implement a Generic Interface

The generic interface IContainer<T> declares Add(T item), Get(int index), and a Count property. Write a Box<T> class that implements it, backed by a List<T>. The tester adds items, then prints the count and some retrieved items. Do NOT write a Main method.

After adding "a" and "b" to a Box<string> the program prints the output shown in Expected Output.

Expected Output:

2↵
a↵
b↵

= newline. The output ends with a newline — print one after the last line.
