Ambiguity in Context free Grammar.
We will see later that the intersection of two context-free languages is not necessarily context-free. Changing the choices made and not only the order they were made in usually affects which terminal string comes out at the end. It is common to list all right-hand sides for the same left-hand side on the same line, using the vertical bar to separate them. Terminal symbols never appear on the left-hand side of the production rule and are always on the right-hand side. What expression does this parse tree generate?
