Describe the term LALR Parser
Describe the term LALR Parser with example.
Expert
The abbreviation of LALR is Look-ahead LR parser. This differs from the LR in the fact that it will look ahead one symbol in the input string before going for a reduce action. Look-ahead aids in knowing if the complete rule has been matched or not.
Example: Consider a grammar G with production
P->AB|ABC
If the Parser shifts the Symbol B it can decrease to P. However if the next Symbol was C then it has not matched the complete rule. The LALR parser will shift one extra token and then take a decision to reduce or shift.
