The following is an algorithm that can convert an expression in infix notation to one in postfix, or RPN. Elsewhere on this site there are some algorithms that do the same thing using a binary tree, but the way I was taught to do it involves using a stack.

Reverse Polish notation (or just RPN ) by analogy with the related Polish notation, a prefix notation introduced in 1920 by the Polish mathematician Jan Łukasiewicz, is a mathematical notation wher...

The shunting yard algorithm is a method for parsing mathematical equations specified in infix notation. It can be used to produce output in Reverse Polish notation (RPN) or as an abstract syntax tre...

In normal algebra we use the infix notation like a+b*c. The corresponding postfix notation is abc*+. The algorithm for the conversion is as follows :

There is an algorithm to convert an infix expression into a postfix expression. It uses a stack; but in this case, the stack is used to hold operators rather than numbers. The purpose of the stack is to reverse the order of the operators in the expression.

e.g. you see 3 4 5 6 7 in this order in the infix expression, but then as an extra check you should see the SAME order in the postfix expression, that is, also 3 4 5 6 7. If not, then something went wrong during your conversion.

I had to do this in my college Java class. The answer isn't so diffcult, just use your Stacks. Mind you this next example is going to be in java, and it was done over a year ago, some things may not be correct because I do not have original...
