* g(h(x)) = x
* としたとき
* [x^N] g^k = k/N [x^{N-k}] (x/h)^N
* を k について列挙 -> h が分かれば解ける
*
* Easy : K=2 のときは f = (x + g) / 2 を代入して
* x = g (1 - g) / (1 + g) を得られる
* -> h = x (1 - x) / (1 + x) になる
* K 一般では h = F(g) 型で表すのは困難
*
* A(h) := g(h(x)) - x = 0 とする
* -> FPS s に対して A(s) = g(s) - x = 2 f(s) - s - x
* が高速に計算できればニュートン法できる
* (自分の代入逆元ライブラリでは g(s) を引数に取るのに注意する)
*
* given s, calc f(s) をしたい。t = f(s) とおくと t は
* t = s + t^K / (1 - t^{K-1})
* B(t) = t^K / (1 - t^{K-1}) - t + s = 0
* なのでニュートン法できる
* ([x^0]A(s) = 0 が必要 -> [x^0]t = 0 がニュートン法の初期解)
