判定方式就是采用层序遍历,对于一个完全二叉树来说,访问每个非空节点之前都不能访问过null。 publicbooleanisCompleteTree(TreeNoderoot){if(root==null)returntrue;Queue<TreeNode>q=newLinkedList<>();q.add(root);booleanflag=false;while(!q.isEmpty()){intsize=q.size();for(intk=0;k<size;k++){Tre...
In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 and 2h nodes inclusive at the last level h. Example 1:
