oopsie…I thought I can do it without gcd but I realized I can’t

In a hurry, I thought that gcd(n,m)=1 only when n%m!=0 || m%n!=0 …(where m,n>=3)
lololol

Don’t be so mean my friend. Just because it went well with you, you want it rated.
Then don’t do any further contest. Codechef will be blessed to get rid of a rating obsessed user like you

How to check that in O(1).
same here…when i saw rating didn’t increased
That was not a good picture he painted there!
yeah easy o(1) solution to check gcd of n&k && m&k==1
No!
And server becomes working not at same time at all places.
Some people may have faced problems like :
- Submitting solution and half hour later they come to know submission has not been made.
- Worrying about rank not been updated for too long during contest.
- Left the contest in-between due to frustration or may be because contest has become unrated.
This time contest has been much easier. Most of students from my college scored near to 300 (who earlier scored 100 or at max 200 points). I think contests should be balanced-neither too easy nor too tough. Sometimes most of people find tough to solve second problem. Yesterday it was much easier to solve at least 400 points.
one nice solution …
If you want to keep contest unrated than reconduct the contest with diff sets of problems.

Would request admin to reply to this thread
Actually, the problem is most of the users have not noticed the announcement and kept coding. This contest could have been made rated as the server errors lasted for about 10-20 minutes. They could have simply extended the time and kept it rated.
There were around 3000 participants in DIV II. 
@admin can keep this rated for DIV II only, if possible.

Agreed.
I faced many issues during the contest but still submitted somehow & solved the most problems I ever have in lunchtime contests to date.
It was really disappointing to see that it won’t be rated after all the patience & effort.
rated for division 1 as well
Yes, it should be rated. It was my best performance so far. It may not be good enough for others, but for me it was the first time I was able to get a decent rank. I feel that I should consider other online coding platforms because this is not nice
We can’t…

I think codechef won’t mind…
You may consider other platforms if you wish to if the only reason is “you got nice rank and contest was unrated”
I wonder how can all of you perform well at same time and get better ranks at same time… Then who did bad than usual ??
I guess it’s because good coders left as aryanc403 pointed out…
