Information Booster:
1. PDA for Palindromes: The PDA uses its stack to store the first half of the input and matches it with the reversed second half.
2. Acceptance by Final State: The PDA transitions to the final state only when the stack is empty after matching all characters.
3. Non-regular Language: The language {wwR} is not regular, as it requires a stack to compare the two halves of the string.
