One famous theory in distributed computing, known as FLP after the authors Fischer, Lynch, and Patterson, proved that in a distributed system with asynchronous communication and process crashes,
每一行命令都是用分号(;)作为结束
对于MySQL，第一件你必须牢记的是它的每一行命令都是用分号(;)作为结束的，但当一行MySQL被插入在PHP代码中时，最好把后面的分号省略掉，例如：
mysql_query("INSERT INTO tablename(first_name,last_name)VALUES('$first_name',$last_name')");

题目大意：给定一棵树，选取两个建立加油站，问说所有点距离加油站距离的最大值的最小值是多少，并且任意输出一种建立加油站的方式。
解题思路：二分距离判断，判断函数的复杂度是o(n)，这样的复杂度应该是o(nlogn)，即使常数系数偏大，但是居然跑了4.5s，也是醉了。 判断函数里面做了3次bfs，但是每次bfs节点最多
