reverse-polish-notation

Created by @Divlo on 29 September 2020.

Instructions :

Your job is to create a calculator which evaluates expressions in Reverse Polish notation (a mathematical notation in which operators follow their operands. It does not need any parentheses as long as each operator has a fixed number of operands).

For example expression 5 1 2 + 4 _ + 3 - (which is equivalent to 5 + ((1 + 2) _ 4) - 3 in normal notation) should evaluate to 14.

For your convenience, the input is formatted such that a space is provided between every token.

Empty expression should evaluate to 0.

Valid operations are +, -, *, /.

You may assume that there won't be exceptional situations (like stack underflow or division by zero).
