Write n as n = 2m + k, where 2m is the largest power of 2 less than or equal to n. K people need to be eliminated to reduce the problem to a power of 2, which means that 2k people must be skipped. The next person in the circle, 2k + 1 people, will be the winner.

What is Josephus Algorithm?

In computer science and mathematics, the Josephus problem (or Josephus permutation) is a theoretical question. The following is the problem statement: There are n people in a circle waiting to be executed. …the task is to choose a position in the initial circle so that you are the last and survive.
