(a) Consider the following grammar: Production. L E return E-E+T E-T TT

(a) Consider the following grammar: Production. L E return E-E+T E-T TT * F T-F F (E) F digit Semantic Actions print(val[top-1]); top = top-1; val[top-2] = val[top-2] + val[top]; top = top-2; val[top-2] = val[top-2] * val[top]; top top-2; = val[top-2] = val[top-1]; top = top-2; According to bottom up evaluation of synthesized attribute compute the value of the input string 3+7*2r using stack, val-stack.
