I made 30+ submissions on q4 (trading) , but was just able to get 87/90 . I think that this problem was more biased towards the accurate precision calculation.
that was the worst problem of the whole challenge and I realised later that there was no point of doing that challenge .

Well not a time waste. Yes, Q4 was a bit annoying and was just based on precision, but scoring high, can earn you an interview call. So its worth it.
Were you able to solve q4?
86/90
- its driving me crazy
any chance for getting a call with global rank 59?

Also could you share your approach for 4th. Got 84

Answer for exercise 4:
I can explained in which way the exercise 4 was wrong (I warned the organization, and they answered me as of I hadnât understood the exercise, so you can always complain to them)
The input and the output were simply not with âexactly 2 decimalsâ but rather with âup to 2 decimalsâ. So the 0 at the end should be omitted.
Took me a few hours to reverse engineer their mistake, so I was quite mad that they answered me as if I was dumb

What do you mean âup to 2 decimalsâ? Can you please elaborate more.
The 0 at the end should be omitted. If you take the example of the exercise where they answer â0.50â, it should instead be â0.5â

But in the sample test cases they displayed their answer as X.0000? If this was the case, then the sample outputs are also wrong.
Yup, my answer passed the âSubmitâ button, but not the âRunâ button
lol
What about the verification process? Do we get mail for verification?
