Event Seating Plan Assistant — illustrative example INPUT Seven fictional guests A–G. Two tables, four seats each. A and B must sit together. Venue confirms Table 1 seat 1 is accessible and suitable for C. No other constraints supplied. RESULT Table 1: seat 1 C; seat 2 A; seat 3 B; seat 4 D. Table 2: seat 1 E; seat 2 F; seat 3 G; seat 4 empty. Checks: A/B together; C in the confirmed accessible position; table capacities respected; all seven guests assigned once. REVIEW A seating plan should honor capacity and supplied accessibility needs. Use only the relationships and constraints provided, and surface impossible combinations before producing a final chart. This is a teaching example, not a live execution record.
