1)The stack may be implemented as an array or a link list. In a stack implemented as an array and a link list, present conditions corresponding to empty (but the requirements to present the conditions can be defined directly.) (2)In the process of changing the formula a/(b+c)*d to a postfix expression using the stack and calculating the postfix expression, show the contents of the stack at each stage.
