The algorithm is a simple way of parsing expressions in infix notation. In this implementation we evaluate the parsed expression making a very basic calculator. The implementation could easily be modified to generate output in RPN.

WebDec 20, 2024 · The Shunting-yard algorithm is an algorithm that was invented by Edsger Dijkstra, that uses stacks and queues to transform a mathematical expression from infix notation to postfix notation.Its name makes reference to a railroad shunting yard because of the similarities between the two. In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation. It can produce either a postfix notation string, also known as Reverse Polish notation (RPN), or an abstract syntax tree (AST). The algorithm was invented by … See more 1. Input: 3 + 4 2.

WebMar 25, 2024 · It works as expected: tree = Tree.build (' (2+3)*2+7*3') assert tree.evaluate () == 31. The final code snippet is essentially Dijkstra’s shunting-yard algorithm. One final remark: parsing and evaluating can be done in one gone, without building a whole expression tree. You could just evaluate an operator and push the result on the stack ...
