15. There are many different names for the same number in the kingdom of mathematics, such as odd numbers, even numbers, prime numbers, palindrome numbers, etc. palindrome number refers to a number where both forward reading and reverse reading are the same, such as 12321 is palindrome number. If a number itself is a palindrome number, its square is also a palindrome number, such a number is called a square palindrome number. For example, 11 is a palindrome number, 112=121 is also a palindrome number, and 11 is a square palindrome number. Please find all square palindrome numbers within 100 to 1000.
