Recursive Depth First Search Algorithm to Compute the Diameter of Binary Tree
Given a binary tree, you need to compute the length of the diameter of the tree. The diameter of a binary tree is the length of the longest path …
How to Balance a Binary Search Tree using Recursive Inorder Traversal Algorithm?
Given a binary search tree, return a balanced binary search tree with the same node values. A binary search tree is balanced if and only if the depth of …
Depth First Search Algorithm with Hash Set to Find Elements in a Contaminated Binary Tree
Given a binary tree with the following rules: root.val == 0 If treeNode.val == x and treeNode.left != null, then treeNode.left.val == 2 * x + 1 If treeNode.val …
Using Depth First Search Algorithm to Delete Tree Nodes with Sum Zero in the Sub Tree
A tree rooted at node 0 is given as follows: The number of nodes is nodes; The value of the i-th node is value; The parent of the i-th …
