dogA,dogB just become friends with dogC,and they want to know when dogC hair colour is,dogc gives
them a list of 10 possible colours.
yellow/brown yellow/gray yellow/red
blue/green blue/brown blue/orange
dogC then tells dogA and dogB separately the first colour and the second colour of her hair respectively
dogA: I don't know what dogC's colour is,but I know that dogB doesn't know too.
dogB: at first I don't know when dogC's colour is,but I know now
dogA: then I also know when dogC's colour is.
so what is dogC's haircolour?
