   How does unique remove a duplicate element from a container?

   • As already stated, unique requires a sorted container. Additionally, unique doesn't actually remove elements from the container. Instead, they are copied to the end, unique returns an iterator pointing to the first such duplicate element, and you are expected to call erase to actually remove the elements.
