Created October 30, 2013 15:01
Imagine people boarding a plane and the first one sits at the wrong place. Every next one sits at his own place if it is available, or at a random place if not. What is the chance that the last person boarded sits at his own place?
import java.util.Arrays;
import java.util.Random;
public class WrongSeatSimulation {
private static final int AVAILABLE = -1;
static boolean simulate(Random rnd, int numberOfSeats) {
int[] seats = new int[numberOfSeats];
Arrays.fill(seats, AVAILABLE);
