Bottom-up parsing techniques are used in this situation .
A bottom- up parser starts at the leaves and grows toward root of the parse tree. As input
is consumed, the parser encodes possibilities in an internal state. The bottom- up parser
starts in a state valid for legal first tokens. Bottom-up parsers handle a large class of
ambigus grammar ko consider krty howy which technique is best to use???
plz discuss today is last date...
Bottom-up parsing is best for ambiguous grammar
thank u Muhammad kashif
for more help visit
I also agree with Bottom-up parsing
why bottom-up parsing is best? any reason plz....
1. error detection is fast than top down parser
2.widely used for computer languages
3.cover the large class of grammars
4.handles the Left-Recursion
5.produce the correct parse without guessing
Thank you Muhammad kashif
