- An expression using the `+' operator in Java produces : (a String expressing the sum of the operands, if they are numbers of different types? the sum of the left and right operands, provided they are numbers of the same type? a concatenation of the left and right operands, provided they are both Strings? a String representation joining the left and right operand, if they are numbers of different types? a String concatenation if one of the operands is non-numeric? ) . The operator also offers a convenient way to turn any value or object into its String representation. This involves specifying :( the object as the right operand and null as the left operand? the object as the right operand only? the object as the left operand only? the object as right operand and the empty string as the left operand? the object as one operand and the empty string as the other?)

Use a deque to implement a program that tests whether a line of text is a palindrome. The program reads a line, then outputs whether the input is a palindrome or not. Ex: If the input is: senile felines! the output is: Yes, "senile felines!" is a palindrome. Ex: If the input is: rotostor the output is: No, "rotostor" is not a palindrome. Ignore punctuation and spacing. Assume all alphabetic characters will be lowercase. Special case: A one-character string is a palindrome. Hint: The deque must be a Deque of Characters, but ordinary chars will be automatically converted to Characters when added to the deque.
