--description--

数字序列游戏以写在一行上的N个数字的序列S开始。两名球员交替轮流。在轮到他时，玩家必须选择并删除序列中剩余的第一个或最后一个数字。球员得分是他所取得的所有数字的总和。每个玩家都试图最大化自己的总和。如果N = 4并且S = {1,2,10,3}，则每个玩家最大化他的得分如下：玩家1：移除第一个数字（1）玩家2：从剩余序列移除最后一个数字（3）玩家1：从剩余序列中移除最后一个号码（10）玩家2：移除剩余号码（2）玩家1得分为1 + 10 = 11.如果两个玩家都遵循，则F（N）为玩家1的得分序列的最优策略S = {s1，s2，...，sN}定义为：s1 = 0 si + 1 =（si2 + 45）modulo 1 000 000 007序列以S = {0,45,2070开头，4284945,753524550,478107844,894218625，...}。给出F（2）= 45，F（4）= 4284990，F（100）= 26365463243，F（104）= 2495838522951。求F（108）。
