4-8 求二叉树高度 (20分)
本题要求给定二叉树的高度。
int GetHeight( BinTree BT );
其中BinTree
结构定义如下:
typedef struct TNode *Position;
typedef Position BinTree;
struct TNode{
ElementType Data;
BinTree Left;
BinTree Right;
};
要求函数返回给定二叉树BT的高度值。
#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(); /* 实现细节忽略 */
int GetHeight( BinTree BT );
int main()
{
BinTree BT = CreatBinTree();
printf("%d\n", GetHeight(BT));
return 0;
}
/* 你的代码将被嵌在这里 */
