C sharp please

The Josephus problem is the following game: N people, numbered 1 to N, are sitting in a circle. Starting at person 1, a hot potato is passed. After M passes, the person holding the hot potato is eliminated, the circle closes ranks, and the game continues with the person who was sitting after the eliminated person picking up the hot potato. The last remaining person wins. Thus, if M=0 and N=5, players are eliminated in order and player 5 wins. If M=1 and N=5, the order of elimination is 2, 4, 1, 5.

Write a program to solve the Josephus problem for general values of M and N. Use a circularly linked list in your solution. Try to make the program as efficient as possible.
