Really disgraceful to see the beginners being fooled by some #so_called_expert_coders_in_their_own_world that they even buy solutions from them just for the sake of earning high ratings and star to look fancy. First of all,it is really bad for someone who is really willing to learn programming as cheating and copying will really not help.Instead it will block the thinking process and make even worse to cope up when exposed to some real life competitions without this shitty external aid.
The purpose of long challenges is to fight till the last moment and get as much problem as u could solve with the best of the capabilities of any particular user. But nowadays,the ball is in the other court.In this process, people attempting honestly will get disheartened as they are not being rewarded as much as they have applied the efforts.
@admin something seriously has to be done about it otherwise,soon the long challenge wont be attempted by good coders and these herd mentality cheaters will be shining in the leaderboard.

I send request to you on discord
My name is revenge#1213
that’s the height of shamelessness , don’t try to be oversmart you can’t solve a cakewalk problem on your own lol!
Let count[i] be the count of numbers with remainder i.
observe that if M%b%a = M%a,
then there always exists an integer k suck M%b = M%a + a * k
because of this rather than iterating over numbers for each a, we’ll iterate over all numbers that can be represented as M%a + a*k. we’ll run a loops backward with a = N to 1 and add the number of b’s for each a, which is the sum of count[M%a + a * k], for k=0 to a * k + M%a <= N. because in this M%b%a = (M%a + a * k)%a = M%a
Note that we only want to b’s that are b > a. So we don’t precompute count
we count as we go. So after we processed current a, we’ll do count[M%a]++.
My code.
Sorry if something wasn’t clear I am not quite used to writing long paragraphs on codechef. You can ask though whatever confuses you.

See the shamelessness of such people who post all solutions. The “Hurray”…
Being coders themselves, they must understand what it feels when one works hard to crack the solution and gets nothing but fall in ratings and people easily get up the ladder by cheating. I think the YouTube channels are the biggest scammers, who leak solutions in every contest, be it long challenge or cook off. Their channels must be reported and banned.

I was casually going through rankings and I encountered a guy who solved 8 questions out of 9 in just 1-2 hours (by the timings of his code submissions) and with 3 different languages. I mean who are you kiddin’ lmao
Its sad such things are happening. I just was hovering over 1st page (first 25) of ranklist and found these similar solutions for VPATH:

They are ranked 1, its shameful. (8/25 suggests on avg 32% plagiarised solns…damn!) @admin
Making the contest unrated will demotivate honest and enthusiastic solvers. The only solution i see is to find plagiarised solutions accurately.

So are we doing anything about this?

I thought I had done quite well getting 530 points, solving all 3 tree problems but not the 2 maths problems. My rank slipped from 88 on day 5 to 1275 at the end, and my overall CodeChef rating has gone down a little. Still I have the satisfaction of really solving most of the problems by myself.

How on earth can you not solve HOWMANY in first time and after 12 days, solve ISS? And that too in a language that you don’t have any knowledge of? Please explain us how is this possible.
