History Exercise

After a very good history class - suceeding a very poor math class - some students from a specific school are in doubt on a simple problem. The teacher asked them about the numeric value (for the sake of simplicity, it must be in decimal and should contain arabic algarisms) of the century of a given year but, as only few students got it, she decided to ask you to help creating a program that does exactly this for educational purposes.

For those who not remember this history class, the century 1, for example, means the years among 1 and 100, the century 2 the years among 101 and 200, the century 3 the years among 201 and 300 and so on.
