Summary:Classification and Regression tree (CART) is an important machine learning algorithm that can be used to create a classification tree (classification trees) or to create a regression tree (Regression tree). This paper introduces the principle of cart used for discrete label classification decision and continuou
Defined:Tree:A tree is a finite set t of N (n≥0) nodes, and when n>0 meets the following conditions:(1) There is only one specific node called root (Root);(2) When n>1, the remaining nodes can be divided into m (m>0) disjoint finite set T1, T2 、...、 Tm, each set Ti (1≤i≤m) is a tree, and is called the subtree of the tree T (subtree).In particular, a

The outer weight line segment tree, the inner interval segment tree can be solved.
Weights are 1~n, so there is no need for discretization.

A Strange tree (s-tree) over the variable set Xn = {x1, x2, ..., Xn} is a binary tree representing aBoolean function f: {0, 1}N→{0, 1}. Each path of the s-tree begins at the root node and consistsof n + 1 nodes. Each of the S-tree ' S nodes has a depth which are the amount o

Question:Two groups of numbers are given on the same binary tree. The first group is output in the inorder order, and the second group is output in the postorder order, build the original binary tree based on the two sets of data, then calculate the sum of numbers from the root node to the path of each leaf node, and output the smallest sum.

problem Description
Given two trees T1 and T2. If T1 can be converted to T2 by several times or so, we call the two trees "isomorphic". For example, the two trees given in Figure 1 are isomorphic because we swap the children of the nodes A, B, and g of one of the trees to get another tree

Binary Tree Preorder Traversal:Given a binary tree, return the preorder traversal of its nodes ' values.For example:Given binary Tree {1,#,2,3} , 1 2 / 3Return [1,2,3] .Note:recursive solution is trivial, could do it iteratively?Recursive pre-order traversal is not used and can be implemented with the help of stacks. For a particular node, the sequ
