Auction Profit Maximizer

An auction house tracks items by 'ItemName ReservePrice CurrentBid'. They want to rank items based on 'Net Profit' (CurrentBid minus ReservePrice). 1. Rank items by Net Profit in descending order. 2. If Net Profit is tied, rank by the CurrentBid in descending order. 3. If still tied, sort alphabetically by ItemName. Input Format: - An integer N. - N lines: 'ItemName ReservePrice CurrentBid'. Output Format: - The sorted ItemNames, one per line. Example: Input: 2 Painting 100 150 Statue 200 250 Output: Painting Statue (Both have profit 50, but Painting is alphabetically first? No, rule 2: Tied profit, then higher CurrentBid. Statue 250 > Painting 150. So Statue comes first.)
