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 …

Algorithm to Construct Binary Tree from Preorder and Inorder Traversal
Given preorder and inorder traversal of a tree, construct the binary tree. You may assume that duplicates do not exist in the tree. For example, given preorder = inorder …
How to Count the Path Sum from a Binary Tree using Depth First Search Algorithm?
You are given a binary tree in which each node contains an integer value. Find the number of paths that sum to a given value. The path does not …
The Process Killing Algorithms using Depth First Search or Breadth First Search (Kill a Process)
Given n processes, each process has a unique PID (process id) and its PPID (parent process id). Each process only has one parent process, but may have one or …
