Bug in Traversables exercies.

[bAmrish]

There seems to be a bug in the Traversables exercises:

Also this assertion seems to be non-deterministic: (totalReduceRightTime > totalReduceLeftTime) should be()
Locally I have tried to run this multiple times and I have varied results. Something to consider when updating this exercise.

Thanks @bAmrish for reporting this. We already fixed it in #97. The new exercise should be available in the next days.

Does it make sense to you?

Thanks @FRosner! Just looked at the change, I agree with your comments. I am glad you are removing the non-deterministic behavior!
