       fected.

       // Run this code

	#include <deque>
	#include <iostream>

	template<typename T>
	void print(T const& xs)
	{
	    std::cout << "[ ";
	    for	(auto const& x : xs)
		std::cout << x << ' ';
	    std::cout << "]\n";
	}

	int main()
	{
	    std::deque<int> numbers;

	    print(numbers);

	    numbers.push_back(5);
	    numbers.push_back(3);
	    numbers.push_back(4);

	    print(numbers);

	    numbers.pop_back();

	    print(numbers);
	}
