WebDerivation. Derivation is a sequence of production rules. It is used to get the input string through these production rules. During parsing, we have to take two decisions. These are as follows: We have to decide the non-terminal which is to be replaced. We have to decide the production rule by which the non-terminal will be replaced. WebJun 3, 2024 · In fact, it generates the language ( a + b) ∗ ( ϵ + c c). You might have missed the basic mindset to write a context-free grammar (CFG). Every non-terminal in a CFG stands for a language. Thinking in terms of languages instead of strings should be more helpful sometimes for constructing the CFG.
