因此,max_heap或min_heap的底层存储结构就是一个数组(数组从编号1开始存储),下面的讲解都将以max_heap为例。对于一个max_heap,主要的操作有四个:make_heap(构造一个max_heap), push_heap(向二叉树添加节点),pop_heap(取最大值,即根节点),sort_heap(对一个max_heap排序)。 2. 基本操作 2.1 push_heap ...

最大堆max-heap:每个节点的键值(key)都大于或等于其子节点键值 最小堆min-heap:每个节点的键值(key)都小于或等于其子节点键值 完全二叉树整棵树内没有任何节点漏洞,这带来一个好处:我们可以利用array来存储所有节点。假设我们动用一个小技巧,将array的#0元素保留(或设为无限大值或无限小值),那么完全二叉树中的...

These algorithms can be used in priority queues, order statistics, Prim's algorithm or Dijkstra's algorithm, etc. As learned earlier, there are two categories of heap data structure i.e. max-heap and min-heap. Let us understand them below but before that, we will study the heapify ...

Heap Dump也叫堆转储文件,是一个Java进程在某个时间点上的内存快照。Heap Dump是有着多种类型的。不过总体上heap dump在触发快照的时候都保存了java对象和类的信息。通常在写heap dump文件前会触发一次FullGC,所以heap dump文件中保存的是FullGC后留下的对象信息。 我......
