josephus(n, k) = (josephus(n - 1, k) + k-1) % n + 1 josephus(1, k) = 1. After the first person (kth from beginning) is killed, n-1 persons are left. So we call josephus(n - 1, k) to get the position with n-1 persons. But the position returned by josephus(n - 1, k) will consider the position starting from k%n + 1. So, we must make adjustments to the position returned by josephus(n - 1, k. Josephus Problem. Given a group of men arranged in a circle under the edict that every th man will be executed going around the circle until only one remains, find the position in which you should stand in order to be the last survivor (Ball and Coxeter 1987).

Finally, the person at position 5 is killed. So the person at position 3 survives. Input.

Josephus had an accomplice; the problem was then to find the places of the two last remaining survivors (whose conspiracy would ensure their survival).

In simple terms Josephus problem is all about finding a position in a circular arrangement which would be safe if executions were handled out using a skip parameter which is known beforehand. For eg : given a circular arrangement such as [1,2,3,4,5,6,7] and a skip parameter of 3, the people will be executed in the order as 3,6,2,7,5,1 and position 4 would be the safe.

For the problem we've investigated for this article, k equals 2 because every second person is killed each time (the odds, as the killers, are spared). If we skip one person, k equals 3, and if we skip two, k equals 4

Thus s+k becomes new s. Going in the same direction this procedure is repeated until one.

Beginning with the first object, we move around the circle and remove every m th object. As each object is removed, the circle closes in.

Josephus Problem. A companion, and others, ended up being trapped in a cave surrounded by Roman soldiers. Instead of surrendering to the foreign soldiers and favouring to kill themselves over being murdered , the men (N) formed a circle, set a specified direction and start location, and then chose a random number (k) from a lot The Josephus problem is another example where technology can play a role in facilitating a proof. The problem is as follows. There are n people around a circle. Starting from person A, count k persons clockwise, and this k-th person is eliminated from the circle. This process continues until only one person is left Furthermore we present a new fast algorithm to calculate j(n; k; i) which is based upon the mentioned bounds. 1 Introduction The Josephus problem in its original form goes back to the Roman historian Flavius Josephus (see ). In the Romano-Jewish conflict of 67 A. D., the Romans took the town Jotapata which Josephus was commanding.
