Conversion of CFG in GNF to NPDA
What is the process of converting a Context-Free Grammar (CFG) into a Non-Deterministic Pushdown Automaton (NPDA)?
In the conversion from CFG to NPDA, what type of automaton is an NPDA?
When converting a CFG to an NPDA, which CFG element is simulated by stack operations (e.g., ε-moves that replace a symbol on the stack)?
During NPDA initialization for CFG simulation, what is typically pushed onto the stack first?
Which normal form for CFGs ensures every production begins with a terminal and thus makes direct CFG→NPDA construction straightforward?
Which of the following languages is context-free and can be recognized by an NPDA but cannot be recognized by any finite automaton?
