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 Edsger Dijkstra and named the "shunting yard" algorithm because its operation resembles that of a railroad shunting yard. Dijkstra first described the shunting yard al… Web9 ago 2024 · from collections import deque import re class ShuntingYardParser: """Converts an infix expression to a postfix expression using the Shunting-yard algorithm""" _operatorPrecedence = {"*": 3, "/": 3, "+": 2, "-": 2} @staticmethod def _tokenize (expression): tokenizer = re.compile (r'\s* ( [ ()+*/-] \d+)') index = 0 tokens = [] while index … Web10 gen 2024 · The shunting-yard algorithm is able to report parentheses problems, but you don't do that.
