Problem: 1678A - Tokitsukaze and All Zero Sequence

Verdict: Wrong answer on test 8

Checker comment: wrong answer 986th numbers differ — expected: '0', found: '-1'

This is my submission: 156338916

1: When scrolling through the submission list, including other contenders, I didn't find another verdict with 'Wrong answer on test 8'. (At least not so far, I will continue looking for it.)

2: I tried to use submit again without a "\n" at the end. Same verdict.

3: Memory looks okay.

4: Time looks okay.

5: When looking through the testcase details, is there a way to see the exact testcase input/output instead of the '...'?

6: Numbers aren't to big for int, so long or long long isn't needed.

7: Could there be a problem with my size_t in the for loop?

8: What am I missing here?

Any help regarding this is highly appreciated.

Kind regards and happy coding,
