The Fibonacci sequence is a set of steadily increasing integer numbers where each number is equal to the sum of the past two numbers. Iinital first two numbers of the Fibonacci sequence are 0 followed by 1.
If any number is equal to the sum of its own digits raised to the power of the digits size is called Armstrong Number. All single digits are armstrong Number because power of those numbers is 1. For example, 371 is an Armstrong number since 3**3 + 7**3 + 1**3 = 371.
A Double linked list is a linked data structure, it built like set of nodes and each node contain three portions (one Data portion & two Node Reference portions).All Node References portion may connected to another node if it really had neighbor node or otherwise Reference portion marked as NULL.Obibsily head node and tail node sigle Reference portion which marked as NULL.
In this article we are going to see how to create antivirus tool - console user interface (CUI).This tool has own scanning algorithm to identify malicious code in each files during scan. The core idea is to search the virus signatures in all files and directory's. Usually, 90% of viruses/worm having own signature (Some repeat text found/visable in all affected files (eg .exe, .vbs, .bat etc..) or archive files) and remain 10% Viruses are identified based on execution behavior.
