usaco dualpal 11难倒不是10进制的回文数？

题目要求输入 n ，s
输出大于s的n个数（满足用2到10间进制表示时为回文数）下面是测试的结果，第二个测试没过。但是11难道不是
回文数吗？请高手解答.

[解决办法]
注意题目要求:
finds and prints (in base 10) the first N numbers strictly greater than S that are palindromic when written in two or more number bases (2 <= base <= 10).

即至少用2种基数表示是回文数的才符合要求.
11只有一种基数(10)表示是回文数,因此不符合题目要求.
