二叉树的遍历 (25分)
前三个遍历用特别特别ez的递归
层次遍历用队列实现
#include <stdio.h>
#include <stdlib.h>
typedef char ElementType;
typedef struct TNode *Position;
typedef Position BinTree;
struct TNode{
ElementType Data;
BinTree Left;
BinTree Right;
};
BinTree CreatBinTree(); //我偏要实现
void InorderTraversal( BinTree BT );
void PreorderTraversal( BinTree BT );
void PostorderTraversal( BinTree BT );
void LevelorderTraversal( BinTree BT );
int main()
{
BinTree BT = CreatBinTree();
printf("Inorder:"); InorderTraversal(BT)
