1、二叉树定义typedef struct BTreeNodeElement_t_ {
void *data;
} BTreeNodeElement_t;typedef struct BTreeNode_t_ {
BTreeNodeElement_t *m_pElemt;
struct BTreeNode_t_ *m_pLeft;
struct BTreeNode_t_ *m_pRight;
} BTreeNode_t;2、求二叉树深度定义:对任意一个子树的根节点来说,它的深度=左右子树深度的最大值+1(1)递归实现如果根节点为NULL,则深度为0如果根节点不为NULL,则深度=左右子树的深度的最大值+1int GetBTreeDepth( BTreeNode_t *pRoot)
{
if( pRoot == NULL )
return 0; int lDepth = GetBTreeDepth( pRoot->m_pLeft);
int rDepth = GetBTreeDepth( pRoot->m_pRight); return ((( lDepth > rDepth )? lDepth: rDepth) + 1 );
}(2)非递归实现借助队列,在进行按层遍历时,记录遍历的层数即可。int GetBTreeDepth( BTreeNode_t *pRoot){
if( pRoot == NULL )
return 0; queue< BTreeNode_t *> que;
que.push( pRoot );
int depth = 0;
while( !que.empty() ){
++depth;
int curLevelNodesTotal = que.size();
int cnt = 0;
while( cnt < curLevelNodesTotal ){
++cnt;
pRoot = que.front();
que.pop();
if( pRoot->m_pLeft )
que.push( pRoot->m_pLeft);
if( pRoot->m_pRight)
que.push( pRoot->m_pRight);
}
} return;
