WebRemoves from the vector either a single element (position) or a range of elements ([first,last)). This effectively reduces the container size by the number of elements removed, which are destroyed. Because vectors use an array as their underlying storage, erasing elements in positions other than the vector end causes the container to relocate all the … WebHere, the idea is to use reverse iterators to construct a new vector using its range constructor.
