This problem is essentially DP.
To speed up the process, I wrote a fast power function for big numbers.
dp[i]=dp[i-1]^n+1 Thanks to the blog http://www.cnblogs.com/staginner/archive/2011/12/17/2290920.html
Each time there is a head and n nodes connected to it.
So each node can choose from all strict n-ary numbers with depths 0 to i-1.
The numbers that can be chosen are dp[i-1], so it is dp[i-1]^n, which can be used for permutations and combinations.
But don't forget about the case of one more node, so we need to add 1.
