31.二叉树的先中后序遍历

作者:互联网

1.先序遍历

#include<stdio.h>
#include<stdlib.h>
typedef int  ElemType;
typedef struct BiTNode{
    ElemType data;
    struct BiTNode *lchild,*rchild;
    
    
    
}BiTNode,*BiTree; 



void PreOrder(BiTree T)
{
    if(T!=NULL)
    {
        visit(T);
        PreOrder(T->lchild);
        PreOrder(T->rchild);
        
    }
    
    
    
}
int main(){
    return 0;
} 

2.中序遍历

#include<stdio.h>
#include<stdlib.h>
typedef int  ElemType;
typedef struct BiTNode{
    ElemType data;
    struct BiTNode *lchild,*rchild;
    
    
    
}BiTNode,*BiTree; 



void InOrder(BiTree T)
{
    if(T!=NULL)
    {
        
        InOrder(T->lchild);
        visit(T);
        InOrder(T->rchild);
        
    }
    
    
    
}
int main(){
    return 0;
} 

3.后序遍历

#include<stdio.h>
#include<stdlib.h>
typedef int  ElemType;
typedef struct BiTNode{
    ElemType data;
    struct BiTNode *lchild,*rchild;
    
    
    
}BiTNode,*BiTree; 



void PostOrder(BiTree T)
{
    if(T!=NULL)
    {
        
        PostOrder(T->lchild);
        
        PostOrder(T->rchild);
        visit(T);
        
    }
    
    
    
}
int main(){
    return 0;
}
