DATA STRUCTURE AND ALGORITHM (Stack)
STACK Stacks are a type of container adaptors with LIFO(Last In First Out) type of working, where a new element is added at one end (top) and an element is removed from that end only. Stack Stack Syntax:- template <class Type, class Container = deque<Type> > class stack; Type – is the Type of element contained in the std::stack. It can be any valid C++ type or even a user-defined type. Container – is the Type of underlying container object. Member Types:- value_type - The first template parameter, T. It denotes the element types. container_type - The second template parameter, Container. It denotes the underlying container type. size_type - Unsigned integral type. The functions associated with stack are: empty() – Returns whether the stack is empty – Time Complexity : O(1) size() – Returns the size of the stack – Time Complexity : O(1) top() – Returns a reference to the top most element of the...
