Corner Cases What if the binary tree is null? Return true in this case. How is the binary tree represented? We use the level order traversal sequence with a special symbol "#" denoting the null node. For Example: The sequence [1, 2, 3, #, #, 4] represents the following binary tree...
Given a binary tree, determine if it is acomplete binary tree. Definition of a complete binary tree fromWikipedia: 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 a...
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...
A binary tree in which for each node, value of all the nodes in left subtree is less or equal and value of all the nodes in right subtree is greater The idea: We can use set boundry for each node. We take C tree for example: For root node, the B (bountry) = [MIN, MAX] nod...

(Note: I get the same error message for both Leaf and Parent.) My current solution is to use sealed instead of final. Unlike final, using sealed actually works! Specifically, the following compiles: trait BinaryTree { trait Payload sealed trait Node sealed case class Parent(left: Option[Nod...

While I can check for Visual C++ 2015 easily by diving into the registry editor, I have trouble checking for 2017. Which is the best way? If you still recommend checking for file version info, which file should I check the version information of, that will ensure forward compatibility?
If you are using this option to check tables, it prevents the check from scanning the rows to check for incorrect links. This is the fastest check method. If you are using this option to repair tables, it tries to repair only the index tree. This is the fastest repair method. ...
