Description
The swap_ranges algorithm exchanges corresponding values in two ranges, in the following
manner:
For each non-negative integer n < (last - first) the function exchanges *(first1 + n) with *(first2
+ n)). After completing all exchanges, swap_ranges returns an iterator that points to the end of
the second container, i.e., first2 + (last1 -first1). The result of swap_ranges is undefined if the
