A new method for handling the left-recursions for top-down parsing is presented. This method preserves the structure of the parse tree specified by the given grammar. Besides, the parsers written based on this method are usually smaller than the parsers written based on the traditional method....
Left recursion and left factoring are two important concepts in compiler design and more specifically for context-free grammars and parsing. Left recursion can be problematic for top-down parsing and needs to be eliminated. Left factoring, on the other hand, improves the efficiency of top-down pa...
Left recursion, in the context of Computer Science, refers to a situation in a context-free grammar where a nonterminal symbol can directly or indirectly derive a sentential form that begins with itself. This can lead to difficulties when using a top-down parser, as it may result in an infi...
