清气爽，焕然一新。然后头发湿漉漉的上网，那时还是163的电话线拨号，吱啊吱啊的
十几声以后，连了上去，先收邮件,查完自己的2个邮箱，都是垃圾邮件，有点郁闷，突
然想：可以去看看陈亮的邮箱吗？怎么搞得，上网的空档停下来就又想到他，现在做什
么事都可能会想到他，真是没出息！但是，他的密码会改吗？想着就顺手开了网易，他
的信箱实在是太好记了，用户名是他名字的拼音，密码是1234321，我的手在键盘上顺
序滑动一个来回，又想，应该进去吗？这样不好吧？想是这么想，但登陆那个键已经点

没反应，怎么会？我心里紧张极了，为什么，密码不对了？也是啊，1234321这样的密

发帖数: 128 | 4 By my understanding,
1234321 is a palindrome where the number of elements is odd (=7).
33 should be treated as a palindrome.
3 (single element) is not treated as a palindrome. |

Some engineers got tired of dealing with all the different ways of encoding
status messages, so they decided to invent their own. In their new scheme,
an encoded status message consists of a sequence of integers representing
the characters in the message, separated by spaces. Each integer is between
1 and M, inclusive. The integers do not have leading zeroes. Unfortunately
they decided to compress the encoded status messages by removing all the
spaces!
