1. Two-Set Inclusion-Exclusion Keeps Both Sizes and Their Intersection

Use the complete indexed finite integer-set family sets=[[0, 1, 2], [0, 2, 3]] in supplied index order. Each set has distinct elements; equal sets at different indices remain separate indexed entries. Every nonempty index subset contributes its intersection cardinality, with positive odd-order and negative even-order sign. Keep zero-size intersections and source increasing-bitmask term order. Give (set_sizes, intersection_size, union_size, alternating_sum, equal).

View answer and explanation

([3, 3], 2, 4, 4, Yes)

Require exactly two indexed sets. Add their sizes, subtract the full intersection size and compare with the actual union cardinality. The exact result, retaining the requested order, is ([3, 3], 2, 4, 4, Yes).
