Extended Euclidean Algorithm in C++
Writing an Extended Euclidean Calculator that calculates the inverse of a modulus can get pretty difficult. However writing a good algorithm and going through step by step can make the process so much easier. So we want to find a’ or inverse of a so that a * a’ [=] 1 (mod b). In other words we are trying to find an integer (a’) when multiplied by a and then divided by b gives you a remainder of 1. In order to find this number(a’), we have to work the Euclidean Algorithm backwards which is referred to as the Extended Euclidean Algorithm.

Modular Exponentiation in C++
Modular Exponentiation is way of calculating the remainder when dividing an integer b (Base) by another integer m (Modulus) raised to the power e(Exponent). Fast modular exponentiation of large numbers is used all the time in RSA to encrypt/decrypt private information over the internet. Whenever you go to a secure site you are using RSA which deals with modular exponentiation.So lets understand modular exponentiation with c++!

Fibonacci Calculator C++
The fibonacci sequence is as follows :
Each successive number is equal to the sum of the two preceding numbers. If you wanted to find the 5th number of the sequence it would be 5.
| F0 | F1 | F2 | F3 | F4 | F5 | F6 | F7 | F8 | F9 | F10 | F11 | F12 | ||||||||
| 0 | 1 | 1 | 2 | 3 | 5 | 8 | 13 | 21 | 34 | 55 | 89 | 144 |
This program is implemented with a double linked list. Each Fibonacci number stored as a sequence of integers inside of a list. For example to calculate the 6th number of the Fibonacci sequence it would start out with f1 and f2 lists that have a single node with 1 inside.

Monopoly City Streets Hack
Monopoly City Streets Vulnerability
The first thing I noticed with this online game is how easy it is to hack other accounts. Normally when you forget your password it is a matter of answering a secret question and the password is emailed to the email on the account. However since monopoly city streets does not require an email address to sign up, it is just a matter of guessing the answer to your secret question. What makes it even easier is there is only one secret question! What is your pet’s name? With just a few common pet names, it doesn’t take long for one to answer that question and be able to change the person’s password.

Looks to Die For
Looks to Die For
Indoor tanning is a refreshing and relaxing experience. Americans alone spend $5 billion annually at roughly 40,000 locations (Bizzozero). The tanning bed has made the dream of a healthier and sexier body realistic. However these rewards come at a price. Tanning is directly linked to skin cancer. It has also been known to be addictive; not a very cheap addiction either. Those that tan often find a dent in their checking account. Although tanning beds can be a pleasant experience, overall it is dangerous to your body and shouldn’t be something in your daily schedule. (more…)
