说明：  精子的分布具有不均匀性，其分布毫无规律，十分散乱，精子的游动方向各不相同，其尾部有的张开，也有的和头部重合，且背景以灰色为主，还有白色等混杂的颜色。本题要求在这样混杂的二十五张图片中求出每张图内所含的精子数目。(The distribution of sperm is not uniform, its distribution is irregular, very scattered, the swimming direction of sperm is different, some of its tail is open, some coincide with the head, and the background is mainly gray, there are mixed colors such as white. In this question, we need to find out the number of sperm in each of the 25 mixed pictures.)

Java实现窗体右键菜单，简约易操作的窗体菜单，这是一个相当易懂的制作实例。 　　super( "右键弹出菜单" ); //调用父类构造函数 　　ChangeColorAction action = new ChangeColorAction(); //菜单项事件处理 　　String[] str = {"Blue","Pink","Yellow","Red","Orange"}; //菜单项名称 　　ButtonGroup colorGroup=new ButtonGroup(); //实例化按钮组 　　popupMenu=new JPopupMenu(); //实例化弹出菜单 　　items=new JRadioButtonMenuItem[5]; //初始化数组 　　for (int i=0;i　　 items[i]=new JRadioButtonMenuItem(str[i]); //实例化菜单项 　　 popupMenu.add(items[i]); //增加菜单项到菜单上 　　 colorGroup.add(items[i]); //增加菜单项到按钮组 　　 items[i].addActionListener(action); //菜单项事件处理 　　} 　　addMouseListener(new MouseAdapter(){ //窗口的鼠标事件处理 　　 public void mousePressed( MouseEvent event ) { //点击鼠标 　　 triggerEvent(event); //调用triggerEvent方法处理事件

说明：  这个是八皇后的代码，用VC写的，使用了c++数据结构，用了递归回溯(eightQueen)
