In the data structure, the heap is actually a completely binary tree . We know that there is also a storage area called a heap in memory, but this is a completely different concept from the heap in the data structure. In the data structure, the heap is divided into Dagen and small Gan , Dagen is the key word of the roo

, Google Analytics can add link tags. Simply put, the variable is added after the target URL of the AD in different channels, and each variable is assigned a value in advance. When a visitor clicks these links. We can clearly distinguish the source and quality of these visitors in the report. Necessary preparations: Adding link tags is a simple task.

However, clicking the link will

Bounce rate is a more interesting measure in website analysis, and also a measure that Avinash Kaushik individual prefers, and there are more discussions on it online.

So far, I know that there are two kinds of heap, one is memory, a common use is dynamic memory allocation (this is the case in C + +), the other is here to discuss a data structure. A, heap In the data structure of the heap is called binary heap, as the name suggests, we can think of it as a complete binary tree, each

1. Little GanIf the root is the child's presence leave the root value of the left child less than the value if the root is the root of the child's right to exist less than the rights of their child.2. Large Root HeapIf the root is a child the presence of the root leaves many names leaving their own child values. Children the value of the root node is greater than the value of the right child.3.

In the previous section we wrote about the tree and the two-tree knowledge.http://blog.csdn.net/wtyvhreal/article/details/43487095The heap is a special complete binary tree.All parent nodes are smaller than child nodes, so a complete binary tree is called the minimum heap, and the inverse is called the maximum heap.A complete binary tree, tuned for the minimum heap
