isEmpty<T> static method

bool isEmpty<T>(CustomSet<T> set)

Checks if a set is empty (cardinality = 0).

An empty set is denoted as ∅ or {}.

Example:

final empty = CustomSet<int>.empty();
final nonEmpty = CustomSet<int>([1, 2, 3]);
print(CardinalityUtils.isEmpty(empty)); // Output: true
print(CardinalityUtils.isEmpty(nonEmpty)); // Output: false

Implementation

static bool isEmpty<T>(CustomSet<T> set) => set.isEmpty;
