std::reverse
The function `std::reverse` is part of the C++ Standard Library, specifically included in the `<algorithm>` header. It is used to reverse the order of elements in a given range, which can be defined by two iterators. This function modifies the original sequence in place, meaning that the elements are rearranged without creating a new copy.
To use `std::reverse`, you simply provide the beginning and ending iterators of the range you want to reverse. For example, if you have a vector of integers, you can call `std::reverse` to flip the order of the integers from the first to the last element. This is a straightforward and efficient way to manipulate sequences in C++.
