std::swap_ranges

Example

print_seq: (comment, seq) = {
    std::cout << comment;
    for seq do (e) {
        std::cout << "(e)$ ";
    }
    std::cout << '\n';
}

main: () = {
    v: std::vector<char> = ('a', 'b', 'c', 'd', 'e');
    l: std::list<char>   = ('1', '2', '3', '4', '5');

    print_seq("Before swap_ranges:\n" "v: ", v);
    print_seq("l: ", l);

    std::swap_ranges(v.begin(), v.begin() + 3, l.begin());

    print_seq("After swap_ranges:\n" "v: ", v);
    print_seq("l: ", l);
}

Output

Before swap_ranges:
v: a b c d e 
l: 1 2 3 4 5 
After swap_ranges:
v: 1 2 3 d e 
l: a b c 4 5
