# Parameters

# Example

#include <experimental/deque>
#include <iostream>
 
template<typename Os, typename Container>
inline Os& operator<<(Os& os, Container const& container)
{
    os << "{ ";
    for (const auto& item : container)
        os << item << ' ';
    return os << '}';
}
 
int main()
{
    std::deque<int> data{3, 3, 4, 5, 5, 6, 6, 7, 2, 1, 0};
    std::cout << "Original:\n" << data << '\n';
    auto divisible_by_3 = [](auto const& x) { return (x % 3) == 0; };
    std::experimental::erase_if(data, divisible_by_3);
    std::cout << "Erase all items divisible by 3:\n" << data << '\n';
