Class Name: MagicSeries
Method Name: lookup
Parameters: int
Returns: int
Define a magic series of numbers to be the series of nonnegative numbers
divisible by 2,3, or 5.
The magic series starts with 0, 2, 3, 4, 5, 6, 8, 9, 10, 12 . . .
Implement a class MagicSeries that contains a method lookup. lookup takes an
index k as a parameter and returns an int that is the kth term of this magic
series of numbers. 0 is the 1st term of the series, 2 is the second, etc...
Here is the method signature:
public int lookup(int k);
k is greater than 0 and less than 1000000.
Examples:
If k=1, the method returns 0.
If k=2, the method returns 2.
If k=20, the method returns 26.
