A trick in step 2.b is to use memorization ( Dynamic programming ) while finding number of employees under a manager so that we don’t need to find number.

We can also use hashing to avoid building a graph. The idea is to first find the starting point. A starting point would never be on ‘to’ side of a ticket.

In order Successor in Binary Search Tree – Binary Search Tree – In order successor of a node is the next node in In order traversal of the Binary Tree.

Java Algorithm – Write a program function to detect loop in a linked list – Linked List – Given a linked list, check if the the linked list has loop or not.

Java Programming – LinkedList in java – Linked List – In Java, LinkedList class implements the list interface.This class consists of the following

Given an unsorted array that may contain duplicates. Also given a number k which is smaller than size of array. Write a function that returns true

Time Complexity: Depends on what sorting algorithm we use. If we use Merge Sort or Heap Sort then (-)(nlogn) in worst case.

Java Algorithm – Write a function to reverse a linked list – Linked List – Given pointer to the head node of a linked list, the task is to reverse

Java Algorithm – Next Greater Element – Stack – Given an array, print the Next Greater Element (NGE) for every element. The Next greater
