看了很久数据结构但是没有怎么用过,在网上看到了关于PHP的数据结构,学习了一下,与大家一起分享一下。
简短不割
class Hero{ public $no;//排名 public $name;//名字 public $next=null;//$next是一个引用,指向另外一个Hero的对象实例 public function __construct($no='',$name='') { $this->no=$no; $this->name=$name; } static public function showList($head) { $cur = $head; while($cur->next!=null) { echo "排名:".$cur->next->no.",名字:".$cur->next->name."<br>"; $cur = $cur->next; } }
//普通插入 static public function addHero($head,$hero) { $cur = $head; while($cur->next!=null) { $cur = $cur->next; } $cur->next=$hero; } //有序的链表的插入 static public function addHeroSorted($head,$hero) { $cur = $head; $addNo = $hero->no; while($cur->next->no <= $addNo) { $cur = $cur->next; } /*$tep = new Hero(); $tep = $cur->next; $cur->next = $hero; $hero->next =$tep;*/ $hero->next=$cur->next; $cur->next=$hero; } static public function deleteHero($head,$no) { $cur = $head; while($cur->next->no != $no && $cur->next!= null) { $cur = $cur->next; } if($cur->next->no != null) { $cur->next = $cur->next->next; echo "删除成功<br>"; } else { echo "没有找到<br>"; } } static public function updateHero($head,$hero) { $cur = $head; while($cur->next->no != $hero->no && $cur->next!= null) { $cur = $cur->next; } if($cur->next->no != null) { $hero->next = $cur->next->next; $cur->next = $hero; echo "更改成功<br>"; } else { echo "没有找到<br>"; } }}//创建head头$head = new Hero();//第一个$hero = new Hero(1,'111');//连接$head->next = $hero;//第二个$hero2 = new Hero(3,'333');//连接Hero::addHero($head,$hero2);$hero3 = new Hero(2,'222');Hero::addHeroSorted($head,$hero3);//显示Hero::showlist($head);//删除Hero::deleteHero($head,4);//显示Hero::showlist($head);//更改$hero4=new Hero(2,'xxx');Hero::updateHero($head,$hero4);//显示Hero::showlist($head);
我是天王盖地虎的分割线
有序的插入的话需要遍历一遍链表,链表的一些知识就不介绍了哈。这里主要分享一下代码。
