创建二叉树

假如我的输入序列为: 2 13 14 5 6 17 8 9 2 3 则我创建的二叉树形如: 2 13 14 5 6 17 8 9 2 3 用二叉表的链接存储结构创建 #include #include using namespace std; struct BinTree { int data; BinTree *Left,*Right; }; void del(BinTree *p) { if(p->Left) del(p->Left); if(p->Right) del(p->Right); delete p; } BinTree *Creat(int *node, int &size, int pos) { if(pos>=size) return NULL; BinTree *t = new BinTree; t->data=node[pos]; t->Left=Creat(node, size, pos*2+1); t->Right=Creat(node, size, pos*2+2); return t; } void DFS( BinTree*p) { if(!p) return ; coutLeft); DFS(p->Right); } int main(int argc, char *argv[]) { BinTree *tree; int node[]={/ 1,2,3,4,5,6,7,8,9,10,11,12,/ 13,45,15,16,17,18,19,20,21,/ 22,23,24,25,26,27,28,29,30,31 }; int size = sizeof(node) / sizeof(node[0]); tree=Creat(node, size, 0); DFS(tree); del(tree); system("PAUSE"); return 0; }
