Forward Lists
Learn about std::forward_list in C++ as a specialized singly linked list optimized for memory and performance. Understand its unique methods for insertion, removal, and merging, and how it differs from other sequential containers in managing data through forward iteration only.

std::forward_list is a singly linked list, which needs the header <forward_list>. std::forward_list has a drastically reduced interface and is optimized for minimal memory requirements.
std::forward_list has a lot in common with std::list:
- It supports no random access.
- The access of an arbitrary element is slow because in the worst case you have to iterate forward through the whole list.
- To add or remove an element is fast, if the iterator points to the right place.
