intersection<T> static method
Returns the intersection of two sets.
Notation: A ∩ B = {x | x ∈ A and x ∈ B}
The intersection contains all elements that are present in both sets.
Example:
final a = CustomSet<int>([2, 4, 6, 8, 10]);
final b = CustomSet<int>([4, 10, 14, 18]);
final result = SetOperations.intersection(a, b);
// result = {4, 10}
Implementation
static CustomSet<T> intersection<T>(CustomSet<T> a, CustomSet<T> b) =>
CustomSet(a.elements.where(b.contains));
