Prefix Calculator:
An arithmetic expression is in prefix form when operators arewritten before their operands. Here are some examples of prefixexpressions and the values they evaluate to:
ExpressionValue1212+2 5153*5 735* + 16 4 +3 180
An expression (such as 12) that begins with an integer is aprefix expression that evaluates to itself. Otherwise, anexpression is a prefix expression if it begins with an operator andis followed by two prefix expressions. In this latter case, thevalue of the expression is recursively computed from the values ofits constituent prefix sub-expressions.
