Step by Step solution about How to resolve the algorithm Parsing/RPN to infix conversion step by step in the Ruby programming language

The code provided is written in the Ruby programming language and uses the RPNExpression class to evaluate a Reverse Polish Notation (RPN) expression and convert it to Infix notation and a Ruby expression. Let's break down each part of the code to understand what it does:

1. RPN Expression:

   • RPNExpression.new("3 4 2 * 1 5 - 2 3 ^ ^ / +"): This line creates a new instance of the RPNExpression class and initializes it with the RPN expression "3 4 2 * 1 5 - 2 3 ^ ^ / +". The RPN expression is a string of numbers and operators separated by spaces.

2. RPN Expression Evaluation:

   • infix = rpn.to_infix: This line calls the to_infix method on the rpn object. The to_infix method evaluates the RPN expression and converts it to Infix notation. Infix notation is a more traditional mathematical notation where operators are placed between operands. The result is stored in the infix variable.

3. Ruby Expression Generation:

   • ruby = rpn.to_ruby: This line calls the to_ruby method on the rpn object. The to_ruby method evaluates the RPN expression and converts it to a valid Ruby expression. The result is stored in the ruby variable.

So, the code creates an RPN expression, evaluates it, converts it to both Infix notation and a valid Ruby expression, and stores the results in separate variables. This allows you to work with the expression in different formats depending on your needs.

rpn = RPNExpression.new("3 4 2 * 1 5 - 2 3 ^ ^ / +")
infix = rpn.to_infix
ruby = rpn.to_ruby
