Erase an element from a map then put it back

Suppose I have a backtracking algorithm where I need to remove an element from a map, do something, then put it back. I am not sure if there is a good way to do it:

func(std::<K, V> map &dict) {
    for (auto i : dict) {
       remove i from dict;
       func(dict);
       put i back to dict;
    }
}

I know there are ways to delete an element from map in here but I am not sure if there are ways to achieve what I described above. I am aware that I can create a new dict in for loop and pass it in func but I am wondering if it can be done using the same dict.
