Mysterious runtime error for 898C

Revision en1, by mistborn, 2017-12-16 20:45:24

I submitted a solution to the Problem C of today's contest that works fine in my computer and other online IDE's that I have checked. But for some reason that I couldn't figure out I get a runtime error in codeforces. Can someone please show me what's wrong with my code. Problem:898C - Phone Numbers Submission:33317474
