WebThe specific algorithm we will describe is called the shunting-yard algorithm: it was devised by Edsgar Dijkstra (one of the pioneers of programming languages and software more generally); the name comes from its connection to how trains are maneuvered around a train yard by “shunting” groups of cars off onto a side-track before re- WebThe algorithm is not a pure operator-precedence parser like the Dijkstra shunting yard algorithm. It assumes that the primarynonterminal is parsed in a separate subroutine, like in a recursive descent parser. Pseudocode[edit] The pseudocode for the algorithm is as follows. The parser starts at function parse_expression. bubbo github https://aminolifeinc.com
