1 votes 1 votes In bottom up parsing , if the same entry has both SR or RR moves then what is the problem? Why is it called a confict ? Why cant we just leave it like that? and Why is it not LR(0)?

In sr conflict means one has already reduced its production and other is being shifting.... In RR both reduced but on same input entry which is wrong means conflict.. And conflict can occur for any one bottom up parsers (LR(0),SLR(1),LALR(1),CLR(1) or LR(1). 1 votes 1 votes Parshu gate commented Aug 16, 2017 reply Follow Share can u plz expain what actually does shifting and reducing means? 0 votes 0 votes Please log in or register to add a comment.
