This homework involves design of PDAs. For all questions, provide the state diagram representation of the PDAs, clearly denoting the start state, the starting stack symbol and final states (if any or if applicable). And, please draw the PDAs consistent with the conven- tions described in the lectures (slides #3#4 and #7 in the PDA lecture notes describe these conventions, and slide #8 shows an example). Ambiguous or different conventions could be wrongly interpreted and may lead to reduction of points to varying degrees depending on the severity of the errors
