    Testing my lambda expression skills a bit more.

    Replaced:

    if (map.get(old) == 1) {
                    map.remove(old);
                } else {
                    map.put(old, map.get(old) - 1);
                }

    with:

    map.merge(old, -1, (a,b) -> {
                    int result = a+b;
                    return (result == 0) ? null : result;
                });
