Password

Mr. Amnésio had great difficulty in keeping passwords. To remind them, he always wore numbers, and writing on pieces of paper, which also lost easily, causing it needed to change the password every time this happened. Tired, he thought in a more practical way: put on paper the next number of password, then he always used the same account to remember the password based on the number written on paper. But he also forgot the formula, therefore, asked you to write a program that, given the number of the paper, enter the corresponding password. Write a program that, given a number, enter their password.
