The main method

In the following code snippet, let's see how Stack is used. A Stack instance is initialized, and references are added to the stack by invoking the Push method. The Pop method is invoked and the output is printed:

// main methodfunc main() {    var stack *Stack = &Stack{}    stack.New()    var reference1 *ReferenceCounter = newReferenceCounter()    var reference2 *ReferenceCounter = newReferenceCounter()    var reference3 *ReferenceCounter = newReferenceCounter()    var reference4 *ReferenceCounter = newReferenceCounter()    stack.Push(reference1)    stack.Push(reference2)    stack.Push(reference3)    stack.Push(reference4)    fmt.Println(stack.Pop(), stack.Pop(), stack.Pop(), stack.Pop())}
