Reverse Polish Notation Calculator Exercise

Reverse Polish notation, also known as Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands

-- https://en.wikipedia.org/wiki/Reverse_Polish_notation

This calculator has a current number, a stack of previous numbers, and keys that modify them:

• Number keys modify the current number in the usual way.
• Operations act on the top elements of the stack, and return their result to the top of the stack.

With the following restrictions:

• Numbers can have at most one decimal dot.
• If an operation is performed while there is a number being input, the number is moved to the stack before performing the operation.
• If an operation doesn't have enough arguments, it does nothing.
• The "√" operation calculates the square root of the top item in the stack.
• The "Σ" operation sums all items in the stack.
• The "Undo" button reverts the last change that was not an undo.
• The "Intro" operation moves the current number into the stack.
