例子，字符串长度为10 6时，那么长度为6的字符串在其中最多出现了10 6 - 7 1次，. 但长度为6的字符串最多有10 7 - 10 6个,一定会出现重复。 用一下等比数列求和公式，发现最后结果为(A X - 1) / (A - 1)，因为题目中给出. 的限制条件，gcd(A, M) = gcd(A-1, M) = 1，可以发现/(A - 1)可以处理成某个非0的. 于是考虑X取何值时，A X % M = 1。 可以用反证法，假设存在一个比phi(M)更小的Y，满足A Y % M = 1，且Y不能够整除. Phi(M)，那么相当于存在A (phi(M) % Y) = 1, 而phi(M) % Y又必然小于Y，那么. 而dp(v1), dp(v2), dp(v3)则分别表示v1, v2, v3以下所有拓扑关系全部满足时. 此时u显然是u这个子树中第一个出现在最后生成的子序列中的数，而v1, v2, v3则为. Dp[u] = dp[v1] * C( v1 1 v2 - 1, v2 ) * dp[v2] * C( v1 v2 v3 1 - 1, v3 ). 总方案数为C(n m - 1, m)。
