Clue binary tree
Clue binary tree
This paper refers to the data structure of Dahua
principle
For a binary list with n nodes, each node has a pointer field pointing to the left and right children, so there are 2n pointer fields in total. The binary tree with n nodes has a total of n-1 branches, that is, there are 2n-(n-1)=n+1 empty finger needle fields. ...
