std::ranges::drop_while_view
constexpr V base ( ) const & requires std:: copy_constructible < V > ;
(1) (since C++20)
constexpr V base ( ) && ;
(2) (since C++20)

Returns a copy of the underlying view.

1) Copy constructs the result from the underlying view base_ .
2) Move constructs the result from the underlying view base_ .

Parameters

(none)

Return value

A copy of the underlying view.

Example

Run this code 
#include <algorithm>
#include <array>
#include <iostream>
#include <ranges>
void print(auto first, auto last)
{
    for (; first != last; ++first)
        std::cout << *first << ' ';
    std::cout << '\n';
}
int main()
{
    std::array data{1, 2, 3, 4, 5};
    print(data.cbegin(), data.cend());
    auto func = [](int x) { return x < 3; };
    auto view = std::ranges::drop_while_view{data, func};
    print(view.begin(), view.end());
    auto base = view.base(); // `base` refers to the `data`
    std::ranges::reverse(base); //< changes `data` indirectly
    print(data.cbegin(), data.cend());
}

Output: 

1 2 3 4 5
3 4 5
5 4 3 2 1
