這兩題的數據比原版鬥地主數據要毒瘤多了......特別是vj的一百個點......

把我在vj上寫的題解發一下吧......

dp[i][j][k][l][m]表示不考慮順子的情況下，（數碼相同的牌有四張的有i種【emmm也就是不算王炸的純炸彈有x個】，以此類推，有三張的有j種，兩張的有k種，一張的有l種，特別的，王的數量為m個）的情況，最少能夠出完牌的次數。
王之所以分開考慮是因為王炸不能算對子，四帶兩對和三帶一對的情況對於王炸要分開考慮，與其特判不如直接新開一維記錄
先預處理出能夠用得到的dp數組的值，然後dfs枚舉順子
本來dp數組中沒有考慮拆牌的情況，只有十多行的狀態轉移，洛谷上面的原版鬥地主能夠a掉，但是洛谷的鬥地主加強版和vijos的鬥地主都不行
於是狠心把所有能夠考慮到的拆牌的情況都寫了進去，令人窒息的五十行if......
其實有的拆牌情況可以不用考慮的，只是我當時實在是不想思考了......
幸好一遍過，沒有怎麽調試，否則我會瘋的......
