常规写法实现手拉手遇三退一的游戏，可以和面向对象思想进行比较着看

public class Count3Quit { public static void main(String[] args) { int[] a = new int[500];            // 500人的环 for(int i=0; i<a.length; i++) { a[i] = 1; } int leftCount = 500; int countNum = 0; int index = 0; while(leftCount != 1) { if(a[index] == 1) { countNum ++; if(countNum == 3) { countNum = 0; a[index] = 0; leftCount --; } } index ++; if(index == a.length) { index = 0; } } for(int i=0; i<a.length; i++) { if(a[i] == 1) { System.out.println(i); } } }}
