Math 在正数时，int(a / b) 和 a // b 通常结果相同，但在负数时可能不同： int(a / b) 是向零取整（trunc）。如果你希望总是向零取整，使用 int(a / b)。 // 是向下取整（floor）。如果你希望总是向下取整，使用 a // b。 另外，取模运算 a % b也遵从 floor法则，a = (a // b) * b + (a % b...

算法复杂度 主定理（Master Theorem） 假设有递归关系式： [T(N) = aT(N/b) + f(N), f(N) = N^{\log_b(a)} \log^k(N)] 其中，$N$为问题规模，$a$为递归的子问题数量，$N/b$为每个子问题的规模（假设每个子问题的规模基本一样），$f(N)$为递归以外进行的计算工作。 则其算法复杂度为： [T(N) = O(N...
