WitrynaConsider all the strings, then check if they can be generated from given grammar or not. Derivation: Grammar Production: S → SaS aSb bSa SS ∈. Option 1: String: … WitrynaHere S produces AB, and we can replace A by a, and B by b. Here, the only accepted string is ab, i.e., L (G) = {ab} Example Suppose we have the following grammar − G: N = {S, A, B} T = {a, b} P = {S → AB, A → aA a, B → bB b} The language generated by this grammar − L (G) = {ab, a 2 b, ab 2, a 2 b 2, ………} = {a m b n m ≥ 1 and n ≥ 1}
