You are given the text ‘IPAddress’. Your task is to check if the given text ‘IPAddress’ is a valid ‘IPv4’ or not.

Conditions for a valid ‘IPv4’ are:

1. Text form of ‘IPAddress’ must be ‘a.b.c.d’
2. The values of a,b,c and d can vary from ‘0’ to ‘255’ and both ‘0’ and ‘255’ are inclusive.

Asked question from fork system call.

You have been given a Binary Tree of 'N'

nodes, where the nodes have integer values.

Your task is to return the ln-Order, Pre-Order, and Post-Order traversals of the given binary tree.

For example :

For the given binary tree:

The Inorder traversal will be [5, 3, 2, 1, 7, 4, 6].
The Preorder traversal will be [1, 3, 5, 2, 4, 7, 6].
The Postorder traversal will be [5, 2, 3, 7, 6, 4, 1].

You are given a Singly Linked List of integers. Return true if it has a cycle, else return false.

A cycle occurs when a node's next points back to a previous node in the list.

Example:

In the given linked list, there is a cycle, hence we return true.

Routing protocol. How link state routing and distance vector routing works.
