Pushdown automata for palindrome
WebAug 18, 2024 · A PDA is non-deterministic. Nondeterministic automata accept a string w if any path along which w might be processed results in w's being accepted. so the PDA will … WebQ. Design a Non-Deterministic PDA for accepting the string L = {(Set of all palindromes over a, b)} by empty stack and by final state. Ans. A string read from left to right and right to left gives the same result is called palindrome. Palindrome can be of two types (a) Odd Palindrome (b) Even Palindrome.
