The header <algorithm>
defines a collection of functions especially designed to be used on ranges of elements.
A range is any sequence of objects that can be accessed through
iterators or pointers, such as an array or an instance of some of the STL containers
.
Notice though, that algorithms operate through iterators directly on
the values, not affecting in any way the structure of any possible
container (it never affects the size or storage allocation of the
container).
