Write a program to verify whether a string is a palindrome string: whether it was read before and after reading it is the same. For example, mom, Dad are palindrome strings. The program receives the string inputted by the user, judges whether it is palindrome string, and outputs the result of judgment. Ignore the size, space and punctuation when verifying the palindrome string. The example output is shown in figure.
