Which of the following describes a handle (as applicable to LR-parsing) appropriately?
A)It is the position in a sentential form where the next shift or reduce operation will occur
B)It is non-terminal whose production will be used for reduction in the next step
C)It is a production that may be used for reduction in a future step along with a position in the sentential form where the next shift or reduce operation will occur
D)It is the production p that will be used for reduction in the next step along with a position in the sentential form where the right hand side of the production may be found

Question

Quizplus · Accepted Answer

A handle in LR parsing is defined as the production that will be used for reduction in the next step, along with the specific position in the sentential form where the right-hand side of this production can be found. This allows the parser to correctly identify where to apply reductions during the parsing process.
