海盗算法

   问：有17个人围成一圈(编号0~16),从第0号的人开始从1报数，凡报到3的倍数的人离开圈子，然后再数下去，直到最后只剩下一个人为止，问此人原来的位置是多少号?

 

int [] people = new int[17];
    int lastPeople = 0;
    public void getTheLastPeople(){       
        for(int i = 0; i < people.length; i++){
            people[i] = i+1;
        }
        int count = 0;
        int countLast = 0;
        int j = 0;
        while(true){
            for(j = 0; j < people.length; j++){               
                if(people[j] != 0){
                    count++;
                    people[j] = count;
                    System.out.println("people[" + j + "] = " + people[j]);
                    if (people[j] % 3 == 0) {
                        people[j] = 0;
                        countLast++;
                        if(countLast == 17){
                            lastPeople = j;
                            return;
                        }
                    }
                }
            }           
        }
    }
