WebApr 17, 2024 · A NPDA is basically an NFA with a stack added to it. The NPDA for this language is identical to the previous one except for epsilon transition. However, there is a significant difference, that this PDA must guess when to stop pushing symbols, jump to the final state and start matching off of the stack. Webδ: Q X ( ∑ ⋃ { λ } ) X Г at most one Q X Г* means we can have possibility of zero move or one move because it is deterministic i.e. it is define as at most one Q X Г*. And we know …
