Write a **program** which takes a `string` containing an equation written in `Reverse Polish Notation` (RPN). It should evaluate the equation, and print the result on the standard output followed by a newline (`'\n'`).
`Reverse Polish Notation` is a mathematical notation in which every operator follows all of its operands. In RPN, every operator encountered evaluates the previous 2 operands, and the result of this operation then becomes the first of the two operands for the subsequent operator. Operands and operators must be spaced by at least one space.
- If the `string` is not valid, or if there is not exactly one argument, `Error` must be printed on the standard output followed by a newline.
- If the `string` has extra spaces it is still considered valid.

Operands and operators must be spaced by at least one space.
The following operators must be implemented : `+`, `-`, `*`, `/`, and `%`.
