There is a mass killing arrangement in a circular conference table. there are 'n' seats and the seats are numbered. person in 1st chair got a knife. if a dispute occurs during the conference, he will kill the person having seat no 2 and pass the knife to seat no 3. 3 will kill 4th and pass it to 5 and so on. clearly, only 1 person will be left after the mass killing process.

The above example can be illustrated as -
1,2,3,4,5

Round 1:

1 Kills 2
3 kills 4
5 left so next round begins from 5

Round 2:
Left1,3,5

5 kills 1
3 left so next round begins from 3

Round 3:
Left 3,5

Finally 3 is the Gladiator!!!

when you kill a man, you're a murderer
Kill many, and you're a conqueror
Kill them all...Ooh...Oh you're a god!

Now, Which Seat you wanna take to be the winner?
