The Food Tiger supermarket wants to reward it's best customer of the day by displaying his/her name on a screen in the store. Your program should repeatedly input a sale amount followed by a customer name until the user enters -1 for the sale amount. Each sale amount and customer name should be placed into a tuple and appended to a list of sales. Design a function called best_customer that takes a list of tuples as a parameter.best_customer should determine which tuple has the highest sale amount and return the name associated with it.
