实现二叉树到对应镜像的转化算法如下: void exchangeBTree(BTRee *root) { BTRee *t; if(root) { t=root->rChild; root->rChild=root->lChild; root->lChild=t; exchangeBTree(root->lChild); exchangeBTree(root->

//注:BiTree为指针类型 BiTree find(BiTree T, int k) { if(k T.count) return NULL; if(T->lchild) { if(T->lchild->count + 2 == k) return T; else if(T->lchild->count + 2 > k) return...

1.基本的构造,以及集中遍历的实现#encoding=utf-8 from collections import deque #定义一个节点类 class Node: def __init__(self,elem=-1,lchild=None,rchild=None): self.elem=elem self.lchild=lchild se
void changeLR(BiTree root){ //请在此处填写代码, 完成二叉树左右子树互换 /********** Begin **********/ if(root->lchild==NULL&&root->rchild==NULL){ return; }else{ BiTree temp=root->lchild; root->lchild=root->rchild;.

knn本文主要结合书中例3-2的数据,构建kd树,并预测点[6.8,0],[2,4.5]的最邻近点。代码实现:import numpy as np class Node: def __init__(self, data, lchild = None, rchild = None): self.data = data self.lchild = lchild
