A charity is having a silent auction where people place bids on a prize without knowing anyone else's bid. Each bid includes a person's name and the amount of their bid. After the silent auction is over, the winner is the person who has placed the highest bid. If there is a tie, the person whose bid was placed first wins. Your job is to determine the winner of the silent auction.
