Stack is a kind of container adapter with LIFO (Last In First Out) operation, where a new element is added at one end (top) and an element is removed only at that end. Stack uses an encapsulated vector or deque object or list (sequential container class) as its underlying container, providing a specific set of member functions to access sections. its death.
Stack Syntax:-
To create a stack, we need to include the header file in our code. Then we use this syntax to define std::stack:
model xss = remove>> class stack;
Type - is the Type of the element contained in the std:: stack. It can be any valid C++ type or even a user-defined type. Container - is the underlying container object type.
Membership Types:-
value_type - The first template parameter, T. It specifies the element type.
container_type - Second template parameter, Container. It indicates the underlying container type. size_type - Unsigned integral type.
The stack related functions are:
empty() - Returns if stack is empty - Time complexity: O(1)
size() - Returns the stack size - Time complexity: O(1)
top() - Returns a reference to the top element in the stack - Time complexity: O(1)
push(g) - Add `g` element to top of stack - Time complexity: O(1)
pop() - Remove top item from stack - Time complexity: O(1)
