Same thing happened to me. Looks like two order iteration is too much to pass the 10th test because n is such a large number. I think you should try reducing the number of iterations. When n is big, there are a lot of combinations you don’t really need to consider. This will make your algorithm more efficient.

There is no errors in the tests. Timing out is not an issue.
