The sweet program

hi

i'm new!!!!

my problem:

n children numbered 1 to n are sitting in a circle. starting at child 1, a sweet is passed. after m passes the child holding the sweet is eliminated. if child x gets eliminated he gives the sweet to child x+1 and leaves the ring. that does not count far a pass. the children in the circle close ranks and the game continues with the child who was sitting after the eliminated child,taking the sweet. assume m is constant for each elimination.
write a program that will determine which child would get the sweet in the end.

I'm totally confused please help!!!!!!
Any assistance will be appreciated:(sweat)::(sweat):

The original problem is the Josephus problem and it is about people being killed one by one; it was not so sweet ;-)

kind regards,

Jos

Use a boolean array and consider it circular, i.e. hopping off from the end brings you back to the first element. If an element is true, the corresponding person is considered to be alive, else hop to the right again until you hit an element that is still true.

You're welcome of course; another possibility is using a BitSet; it has a method that can find the next set bit for you; a BitSet can be interpreted as a boolean array.
