Nettet21. mai 2015 · The right hand side of several productions appear on the left-hand side as in production 3 (And this property is called left recursion) and certain parsers such as recursive-descent parser can't handle left-recursion productions. They just loop forever. NettetRecursive descent is a top-down parsing technique that constructs the parse tree from the top and the input is read from left to right. It uses procedures for every terminal and non-terminal entity. This parsing technique recursively parses the input to make a parse tree, which may or may not require back-tracking.

NettetLeft factoring is a grammar transformation that is useful for producing a gram-mar suitable for predictive, or top-down, parsing. When the choice between two alternative ^-productions is not clear, we may be able to rewrite the pro-ductions to defer the decision until enough of the input has been seen that we can make the right choice.
