原创 快用双拼！
双拼，顾名思义，用两个按键来实现任何汉字的拼音输入。一般来说就是声母一个，韵母一个。由于每个字都对应两个按键，所以打起字来十分有节奏感。对于只有韵母的特殊情况，声母用 o 来替代。如“啊”就是oa，“安”就是oj。重码率和全拼差不多，尤其在支持模糊输入的情况下。支持全拼双拼混合输入。

more最近看了电影《千钧一发》，发现电影的英文名叫 Gattaca，这并不是英语中既有的单词，于是我开始思考它的由来，发现这个单词其实挺有意思。

原创 contest: Codeforces Round #297 (Div. 2), problem: (B) Pasha and String
转置与顺序无关，比如 1 2 3 4 5 和 5 4 3 2 1的转置顺序结果是一样的，所以先进行排序，删除成对的且相同的，同一部分转置两次相当于没转；即 1-10,3-8,4-7,5-6 先看前两个 3-8转了两次 所以只需要转置 1，2,与9,10即可 同理 只要交换4与7即可。于是要进一步优化，例如一个长度为10的串，输入 5 4 3 2 2 1 先排序，删掉两个2，剩下 1 3 4 5。其实还可以简化，刚开始嫌麻烦就这样交了..于是超时了..刚好卡在最后一组数据上..
