Question: For each of the below three problems, draw the state diagram of a pushdown automaton. (a) {ww starts and ends with same symbol } (b) {w the length of w is odd } (c) {w\w = WR, i.e., w is a palindrome }. For instance the word noon is a palindrome because reversing the letters results in the same word.
