Problem 1986C Submission: 304652327 For the test case: 7 10 traktor 7 6 5 4 3 2 1 6 4 2 codeforces

My system gives the correct output of ccdeefo but the judge reverses the entire thing and outputs ofeedcc

I have tried a lot of things but i genuinely do not understand why it reverses my output for that one test case. I really need any help i can get.
