B. Om Nom and Dark Park 在满二叉树上的某些边上添加一些值.使得根节点到叶子节点的路径上的权值和都相等.求最少需要添加多少. 我们利用性质解题. 考察兄弟节点.由于他们从跟节点到父节点这路径是相同的,所以需要添加的值为 2*max(lch,rch)-lch-rch; 同时将max(lch,rch)累加到父节点. 思路是最重要的.有时候不是聪不聪明的问题,而是会不会思考的问题. #include <iostream> #include <cstdio>

LockSupport类是Java6(JSR166-JUC)引入的一个类,提供了主要的线程同步原语.LockSupport实际上是调用了Unsafe类里的函数,归结到Unsafe里,仅仅有两个函数: public native void unpark(Thread jthread); public native void park(boolean isAbsolute, long time); isAbsolute參数是指明时间是绝对的,还是相对的. 只两个简单的接口,就为上层提供了强大的同步原
