Haven’t got reply on my request of joining problem setting (before one month)…

“Top 10 performers get laddus”. Did Codechef update their rules? I hope it’s just a typo :confused:

How many problems?

5

yeah I also think so because contest page shows different prizes according to division…

6

Can someone from Problem setting panel explain the sample test case of Reach Equilibrium as it seems a little unclear…
Please provide P and Q instead of the final answer for better understanding if possible…
Thanks…

PS: I commented on question 17 hours ago but haven’t got a reply still…
Many other people also commented about it…

8

also maybe I think @mention is not working in comments on problem page…

Do the magnitudes need to be integers in this problem, or they can be any real numbers. (According to the question it seems that they can be any real values but I doubt that.)

10

I am not having any faith in codechef anymore. Like no reply in 48 hours? No explanation of sample test case…And forget that even @admin is not worried to look at the announcement post once in a day.
Seriously why??

Can someone tell about notification “You are not allowed to check this content.” in July long 2018 contest…
Thanks…

Commented on Magic Set problem but no reply in 10 hours.

13

Please share Screenshot.

14

explaining or disclosing P Q will be a spoiler maybe… and hence codechef is not replying… though I feel they should reply that “we can’t do that now” …

15

We(teja349 and me) decided to don’t add explanation for this problem, I’ll explain why after the contest. Anyways, we added P and Q now.

@pshishod2645 sorry for the delay, I’m a bit busy with my university. Yes, magnitudes can be any real numbers(it’s written in the statement)

Thanks @mgch atleast you replied with “You can’t provide explanation, as it may be a spoiler”,. Btw I myself found the value of P and Q by just running a loop of i, and j and checking i/j mod (10^9 + 7), :stuck_out_tongue:
