LuckyLand Lottery is a problem directly related to Josephus problem!!!
In short:
There are N peoples (N > 0) arranged in a loop (_peoples are numbered from 1 to N_) so that after Nth person 1st person comes. In each lottery round the 2nd person wins starting from random number P (0 < P <= N), then next round starts from that position where it was ended before. Given the value of N and P. You need to find the person who wins at last.
