kalk

A CLI calculator written in Kotlin.

Notable features

• This program implements the shunting-yard in Kotlin as an extension method on String - see String.toRPNExpression().
• Also implemented is an RPN expression evaluator which is fairly succinct thanks to the use of the Operator sealed class which can be found here.
