Get Century From Year

In this task, implement a getCentury() function that:

• accepts the year variable;
• returns a century this year is in.

Note that the first century begins from the year 1 and continues up to and including the year 100, the second from the year 101 to the year 200, and so on.

For example:

getCentury(1705) // 18
getCentury(1900) // 19
getCentury(1601) // 17
getCentury(2000) // 20
