Which mechanism explains why a LALR(1) parser can parse all context-free languages generated by a formal grammar that allows for deterministic parsing with a one-token lookahead?

💡 Explanation

LALR(1) parsers merge states with the same lookahead sets to minimize the parsing table, and this state-transition table minimization allows them to handle a broader class of context-free grammars than SLR(1) parsers, because fewer states lead to fewer conflicts; therefore, LALR(1) parsers are more powerful than SLR(1) parsers rather than relying on unlimited memory or backtracking.
