Collections.cs

/*
 * Collections in C# are used to store a collection of objects or data.
 * It is a more flexible way to store data than arrays.
 * Unlike arrays, collections can grow and shrink dynamically as the needs of the application change.
 * For some collections, we can assign a key to any object that we put into the collection, so that we can retrieve the object by using the key.
 * 
 * A collection is a class, so we need to create an object of the collection class to use it.
