Practice constructor chaining by building an Account class that offers flexibility in how accounts are created. Use overloaded constructors to allow for different initialization scenarios, and ensure all constructors ultimately delegate initialization to a single constructor to avoid code duplication.

• The Account class must have three constructors: a default constructor, a constructor that takes an accountNumber, and a constructor that takes both an accountNumber and a balance.
• The default constructor must set both AccountNumber and Balance to zero.
• The constructor with one parameter must set AccountNumber to the provided value and Balance to zero.
• The constructor with two parameters must set AccountNumber and Balance to the provided values.
• All constructors must use constructor chaining so that only one constructor contains the actual assignment logic.
• Do not duplicate assignment code across constructors.
