the level of the contest is too hard 
For the Fibonacci problem sorting the frequencies and checking the condition didn’t work for me. Did it work for others? If no, why?
Thank You very much for bringing up the Editorials as soon as the contest ended.
One of the best contest i too part in!!
I thought it was tough for me in the beginning but was little surprised when I looked on the number of submissions. I kept trying and managed to get one correct answer at the end. The clock question was very well set, easy to code but tricky logic. Thanks for publishing editorials so fast 
Also why is the rating predictor tool http://codechef-rating-predictor.7e14.starter-us-west-2.openshiftapps.com/contest/COLE2018/all/ showing
Error: No contest predictions found for such contest!
Is it because there is some mistake in link?
when Rating will be update for this contest

Hello, I did not get the laddus for this contest.
Maybe the triangle problem was a bit too hard; and the cakewalk problem turned out somewhat not ‘cakewalk’. Other than these two, were the questions too hard?

That is because in a permutation that satisfies the condition, F_i > F_{i-1} for all i \ge 3. But F_2 > F_1 is a wrong assumption.
Thanks for replying! Could you give me an example of frequencies where sorting them does not find a solution?
Sure, (1, 2, 3, 4) for example. The permutation that satisfies the relation is (2, 1, 3, 4).
Wow 
I see, didn’t think about this. Thanks!
A lot of people didn’t think about this 
Including me!

use the databread rating predictor.
It deviates a lot from original ratings.
I don’t think it’s working for any contest at the moment. I can see a “Application is not available” message.
You could contact @vsp4, I think he is the developer of the site.
