原创 Manacher算法
Manacher算法是专门用来处理回文的一种算法，其主要的作用是找出一个字符串里面最长的一个回文。要用到这个算法，首先要做的就是改变原来的字符串，就是在原有的字符串中，每两个字母之间都插入一个字符串里面没有的符号。比如：如果这个字符串是由26位字母组成的，那么就在第一个字母前和最后一个字母的后面以及每两个中间都插入一个#。举个栗子：s[]=”aaaaa”，那么这个字符串就改成：s[]=”#a#a#a

原创 Codeforces Round #367 (Div. 2) D. Vasiliy's Multiset（字典树模板）
这里戳题目题意：首先给你一个集合，这个集合里面一开始只有零（一开始是有零的，别用个空的集合，并且这个集合允许有重复的值），然后有三种操作，如果输入时加号，就往这个集合新增一个数字，如果是减号，就把减号后的那个数字从集合里面去掉，如果是问号，就从集合里面找一个数，这个数字和问号后面的数字异或的结果是最大的。异或：意思是说有两个数字，如果不是二进制，就转化成二进制，然后两两比较，相同为零，不同为一，再转
