求1-20000之间的平方回文数

回文数也叫对称数，是指这类数的各位数字具有对称性，例如12121，通常，可以通过使用任何一个数字与其倒序数相加，再依次执行下去获得，例如：96+69 165，165+561 726，726+627 1353，1353+3531 4884。但是也有某些数字目前为止还不能验证是否可以通过上述操作获得回文数，例如数字196。平方回文数是指这类数字即是回文数，又是某个自然数的平方数，例如121，就是11的平方数，同时也是回文数。可以编写程序，通过遍历获得平方回文数。-Find the number of square returns between 1-20000

The number of palindromes is also known as symmetry, that is, the number of each digit of such a number of symmetry, such as 12121, usually, you can use any number and its inverse number is added, followed by the implementation of the next to get, for example: 96+69　 165 , 165+ 561　 726, 726+ 627　 1353, 1353+ 3531　 4884. However, there are certain numbers that have not been verified so far as to obtain the number of palindromes, such as the number 196, by the above operation. Square palindrome is the number of such palindrome that is the number, but also the square of a natural number, such as 121, is the square of 11, but also palindrome number. You can write a program to get the square palindrome by traversing.
