Types

type Stack

type Stack struct {
	// contains filtered or unexported fields
}

Stack is

func NewStack

func NewStack() *Stack

NewStack is the factory method to instantiate a new Stack

func (*Stack) Pop

func (s *Stack) Pop() (f float64, err error)

Pop pops a value from the end of the stack and returns it. If the stack is empty it will raise an error

func (*Stack) Print

func (s *Stack) Print(output io.Writer)

Print is a helper method to print the current stack in human readable format with a maximum of 10 decimal places to the provided io.Writer interface.

func (*Stack) Push

func (s *Stack) Push(f ...float64)

Push pushes a float64 to the end of the stack

func (*Stack) PushString

func (s *Stack) PushString(str ...string) (err error)

Push pushes a string to the end of the stack

func (*Stack) Reset

func (s *Stack) Reset()

Reset resets the stack to an empty slice of float64 values

func (*Stack) Size

func (s *Stack) Size() int

Size returns the length of the current stack

func (*Stack) String

func (s *Stack) String() string

String writes the output of the print function to a buffer and returns a serialized string
