Show that the following grammar is ambiguous by drawing two different parse trees. Note: you need to make a string of the terminal symbols: a, b, and/or c two produces two parser trees. S = S 'b' S | 'a' | 'c' Note for Antlr User: Antlr may not be able to produce two different parse trees. In this case you need to draw the second tree
