思路分析: 用两个stack来维护这个MinStack结构。1个stack用来正常进行stack的push pop等操作。另外1个stack用来维护min.每次对stack进行pop或者push时,也对min_stack进行相应操作。 C++代码示例: #include <stack> using namespace std; class MinStack { private: stack<int> stk; stack<int> min; public: void...

stack翻译为栈,是STL中实现的一个后进先出的容器。要使用 stack,应先添加头文件include<stack>,并在头文件下面加上“ using namespacestd;"1. stack的定义其定义的写法和其他STL容器相同, typename可以任意基本数据类型或容器:stack<typename> name;2. stack容器内元素的访问... c++ 开发语言 后端 #include 入...
对于局部变量,它的存储在栈中分配,如果它是一个 array, struct, union, class 统称复合类型,那么它的每个成员都在栈中分配。它们的 size 是编译时确定的,所以在栈中构造,编译时即可预留空间(通过减小 esp/rsp 寄存器的值),内存分配的效率比在堆中高,因为堆要在运行时执行分配算法。但前提是,由于 C/C++ 有指...
