Learner Error: Grader timed out Course 2 Week 2 UNQ_C2

The test part of second exercise takes too much time (the result is success at the end). I checked but could not see the problem. Because of that grader fails. Can anyone help.

Hi O_Ceylan,

As a belated reply: I hope you were able to resolve this. If not, let me know and I will see if I can help in resolving this.
