+Vse skupaj zapišemo takole: [("Ana", "torta"), ("Berta", "krof"), +("Cilka", "kava"), ("Ana", "kava"), ("Berta", "-krof"), ("Cilka", "-torta"), +("Berta", "torta")]. Seznam torej vsebuje pare nizov (oseba, jed), +pri čemer se jed včasih začne z "-", kar pomeni, da stranka prekliče naročilo te +jedi oz. pijače.

+ +

Napiši funkcijo orders(s), ki prejme takšen seznam in vrne +slovar, katerega ključi so imena strank, vrednost pri vsakem ključu pa je +seznam vsega, kar mora stranka na koncu dobiti.
