There are many similiar codes in Problem E of Round 923(Div 3) which cause unfair to genuine coders.
Here is the plagiarized code:
#include <bits/stdc++.h>
using namespace std;
#ifdef LOCAL
#include "algo/debug.h"
#else
#define debug(...) 42
#endif
int main() {
ios::sync_with_stdio(false);
cin.tie(0);
int tt = 1;;
cin >> tt;;
while (tt--) {
int n, k;
cin >> n >> k;
vector<int> v(n);
vector<int> a(k);
a[0] = n;
a[1] = 1;
for (int i = 0; i < k; i++) {
int sign = (i % 2 == 0 ? -1 : 1), move = 0, mn = n + 1, mx = 0;
for (int j = i; j < n; j += k) {
v[j] = a[i] + sign * move++;
mx = max(mx, v[j]);
mn = min(mn, v[j]);
}
if (sign == -1) {
if (i + 2 < k) {
a[i + 2] = mn — 1;
}
}
else {
if (i + 2 < k) {
a[i + 2] = mx + 1;
}
}
}
for (int &it : v) {
cout << it << ' ';
}
cout << '\n';
}
return 0;
}
Here are the submission Links:
245224542 (Added Unnecessary variables)
245192424 (Changed to Perl)
and many more similiar submissions.
We know that the blog gets downvoted by many cheaters.
MikeMirzayanov plz take some actions against cheaters.
Auto comment: topic has been updated by whitepalace (previous revision, new revision, compare).
i found more such ones what you think of these ? time of submission etc i considered. 245220824 245222953 245222848
There had been other rule violations in this round. Check
yes also in my comment first and last one has made unnecessary variables uses too in both problem D and E . Both are exact same sols.
245222710 all the cheaters have this same code for problem D. Eg: 245206997
from here one can observe that they cheated from there as there same sols got posted. With just minor variable changes plus some extra variables which have no meaning like in the 245222848 submission he/she used two for loops instead of one just to avoid getting detected. similarly 245220824, Thanks to othmaine for sharing the link with me from where sols the cheaters got .
I request MikeMirzayanov to pls take action for the above users and also from op.
no one got caught will this be not properly checked like in both op and mine ones?
If cheaters were removed, my ranking would improve by thousands for sure.
hey guys I am new in cp , I have only participated in hello 2024 and the yesterday's div 3 contest. But for the hello 2024 , I got rated +373 but for yesterday's contest (923) I have solved 1 problem correctly (the 1st one) but it didnt give me any rating and in profile it also doesnt show I have participated in the contest. Why is that?
its still undergoing sys testing
wait it until tomorrow. you'll have your rating
Pls block them if they did it more than once after warning
I believe there will be a temporary rating rollback for this round to remove those cheaters' submissions
stop crying for once bruhh
when the logic is the same for different people it is probably they will have code that will look similar i don't think you can tackle that problem.
I think there should be a report option so the team can take appropriate actions against them..
an action should be take against them.cheating detection system should be made more powerful.
245183505 look at this users submissions
Hope so when temp rating roll back happens then all those cheaters links posted here gets penalised.
most of the solution are not yet skipped in the op. 245222848 245220824 245222953 like these ones of mines too .I request MikeMirzayanov to please look into these too . system tests might fail to recognize them but you will def understand after seeing their solutions.
