Josephus attended a party where they had a rather strange raffle. Everyone was to stand in a circle, and every Mth person was to be eliminated until only one person was remaining, who won the lawnmower. Write the function Josephus, which takes as parameters a vector representing the N guests at the party in the order they line up for the raffle, and the integer M, giving which person will be eliminated at each turn. Your function should return a string giving the name of the winner of the raffle (the last person standing). Hint: While there is a mathematical solution, a queue will be much more straightforward.
