class DynStack

{

private:

struct StackNode

{

T value;

StackNode *next;

};

StackNode *top;

public:

DynStack() {top = nullptr; }

void push(T); //This is the one you will write

void pop(T &);

bool isEmpty();

};

// Member function push pushes the argument onto the stack.

// YOU CODE THIS FUNCTION BELOW

//***************************************************

// Member function pop pops the value at the top
