Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Input {receipts, staff: [[name, hours, reported_tips]]} with positive total hours. Target = 8% of receipts. Shortfall = target - total reported; none -> {}. Each employee's share = target*hours/total_hours; employees reporting less than their share get deficit = share - reported. Shortfall is allocated in proportion to deficits, each rounded half-up. Return {name: cents}.

Why this case matters

Tip allocation assigns reported income on W-2s, and only employees under-reporting their share receive allocations.
