I have a task if you are interested, but I didn't bother to login 
to create it.
So if you like, you can create the page...

Here it is:
In a sequence of a million random integers, return the length and 
the indexes of the longest duplicate sequence (display indexes 
counting from one, not zero).

In order for everybody to start with the same random sequence, it 
may be useful to specify a simple implementation for the 
generating function.
