Java language to achieve binary heap printing code sharing

Binary heap is a special heap. Binary heap is a complete binary tree (binary tree) or an approximate complete binary tree (binary tree). There are two types of binary heap: maximum heap and minimum heap. Maximum heap: the key value of the parent node is always greater than or equal to the key value of any child node; minimum heap: the key value of the parent node is always less than or equal to the key value of any child node.

Printing binary heap: using hierarchical relationships

Here, I first sort the heap, and then execute the print heap method printastree() in sort

Execution results:
