Removing

The function Big_set.remove creates a big set containing the elements of a given big set, without a given element. If the element is not already present, the new big set is the same as the old one, as expected.

const my_big_set: big_set<int> = Big_set.literal(list([3, 2, 2, 1]));

const new_big_set = Big_set.remove(3, my_big_set);

const contains_3 = Big_set.mem(3, new_big_set); // == false
