template<typename Semilattice>
class sparse_table;

sparse_tableは代数的構造の区間和を計算する静的なデータ構造です


templateパラメータ
-Semilattice
結合律　(a * b) * c = a * (b * c)
交換律　a * b = b * a
冪等律　a * a = a
以上の性質を満たす構造体
operator+で演算が定義されている必要があります
演算の対象にできる適当な値で初期化するデフォルトコンストラクタが必要です


メンバ関数
-(constructor)(std::vector<Semilattice> array)
arrayの要素からsparse_tableを構築します
時間計算量:O(NloglogN)

-range(uint32 begin, uint32 end)
半開区間[begin,end)の区間和を返します
時間計算量:O(1)


※N:arrayの要素数
※__builtin_clzの時間計算量をO(1)と仮定
※Semilattice::operator+の計算量をO(1)と仮定
