判断一棵树是否为完全二叉树
1 #include <queue> 2 using namespace std; 3 void IsComplete(node* root) 4 { 5 queue<node*> q; 6 q.push(root); 7 while(!q.empty()) 8 { 9 root = q.front(); 10 q.pop(); 11 if(root) 12 { 13 q.push(root->lchild); 14 q.push(root->rchild); 15 } 16 else 17 { 18 while(!q.empty()) 19 { 20 root = q.front(); 21 q.pop(); 22 if(root) 23 { 24 printf("No\n"); 25 return ; 26 } 27 } 28 } 29 } 30 printf("Yes\n"); 31 }
