Suisse Global Coding Challenge: Q4 - Risk Trading

I haven’t been able to get full score in this question (tried multiple languages). Got 84/90. Not a lot of people on the leaderboard have solved it either. I’m wondering if this is due to a problem with the question. Can anyone please confirm this?

I don’t think so there is a problem with the question cause many had solved it.

huh. I thought it might be because the testcases are randomly evaluated on each submission.
