cpp #include <iostream> int main() { const int n = 10; // 数组长度 double arr[n]; // 定义一个长度为n的double类型数组 // 计算并输出数组占用的内存空间大小 std::cout << "Array size in bytes: " << sizeof(arr) << std::endl; std::cout <<...
这里介绍一种实现,Double-Array Trie(双数组字典树),其实它就是双数组,跟树结构没啥关系。他能在一定程度上减少内存的浪费。 两个数组,一个是base[],另一个是check[]。设数组下标为i ,如果base[i], check[i]均为0,表示该位置为空。如果base[i]为负值,表示该状态为终止态(即词语)。check[i]表示该状态...
