Multiset in C++ STL
C++ multisets are STL containers that store elements of the same type in sorted order, where multiple elements can have equivalent values. In other words, duplicate values are allowed. Like C++ sets, the value of each element acts as its own key. Multiset Properties Elements are referenced by their key and not by their absolute position in the container. Elements are stored in a…
Set in C++ STL
Sets are a type of associative containers in which each element has to be unique because the value of the element identifies it. The values are stored in a specific order. The value of the elements in a set cannot be modified once in the container (the elements are always const), but they can be inserted or…
Stack in C++ STL
Stacks are a type of container adaptors with LIFO(Last In First Out) type of working, Where insertion and deletion is always performed at the top of the stack. For creating a stack, we must include the <stack> header file in our code. We then use this syntax to define the std::stack: Functions of stack: empty…
Priority Queue in C++ STL
Priority queues are a type of container adapters, specifically designed such that the first element of the queue is the greatest of all elements in the queue and elements are in nonincreasing order (hence we can see that each element of the queue has a priority {fixed order}). This context is similar to a heap, where…
