@admin these all are submission for EVENXOR .pls check all these solutions are exact same.also check last 10 minutes submissions of all questions you will find many same solutions.
By checking AC solutions submitted few minutes before the end of the contest
I also see that the submission rate increases very sharply when the contest is about to endā¦ I used to think that some sort of logic clicks into their mind to solve the question as the contest approaches its endā¦
REPORT for user @anon61691861
He has been cheating for a very long time . @admin please look into it. He obfuscates his code by adding unnecessary variables . Moreover his submissions are very similar to others.
Here are a few examples :-
CONTEST INFI21B
PROBLEM MARBLE
Look at his submission CodeChef: Practical coding for everyone
See lines 17,18,23,26,40,51.This is a clear indication of plagiarism .
Also his remaining code matches exactly with others
Here a few I found. There are many more

@admin @shaily_adm
I tell you, why cheating is on the peak nowadays. These guys cheat to show great ratings/stars/ranks on their resume to get shortlisted in placement companies. They are not afraid of getting their rating down to 1 star due to MOSS plagiarism checker because the moment, MOSS catches their plagiarism, its too late, as plagiarism is checked in the range of 6 months to 1 year or more, and, till then, the cheaters gets placed in the company. So, itās a big loophole, that all are misusing!
Cheaters in Div1 too :

how??? bro interviewers ke samne kaise laptop kholega koi banda
@admin and all other higher officials of codechef. In last 5 minutes of the contest, the code of " Non Zero Subarray Xor"
was made public by someone. and all the submissions done in last 4-5 minutes have the same code almost (you can check).
THis same thing was done in " Maximising Vacations"
SO PLEASE TAKE SERIOUS ACTION AGAINST THEM .
@codechef @admin
mourya_satyam | CodeChef User Profile for Satyam Mourya | CodeChef and amiy_tiwari | CodeChef User Profile for Amiy Tiwari | CodeChef seem suspicious, but not sure. Requesting someone from the community to look at their submissions and find any concrete evidence if they can.
Yup, here it is:
https://www.codechef.com/viewsolution/56770904
https://www.codechef.com/viewsolution/56801065
They both are quite similar. I am attaching the exact and nearly same snippets below.
ind = n//2
ans = []
a1 = a.copy()
b1 = b.copy()
i=ind
if a[i]==a[i+1]:
if a[:i+1].count(a[i])!=i+1:
ans.append([1,i+1])
for j in range (0,i+1) :
if (a[j] == '1') :
a[j] = '0'
else :
a[j] = '1'
else:
ans.append([i+2,n])
for j in range (i+1,n) :
if (a[j] == '1') :
a[j] = '0'
else :
a[j] = '1'
Other guyās code: (very cleverly wrote a function to flip)
idx=n//2
ans=[]
i=idx
if a[i]==a[i+1]:
if a[:i+1].count(a[i])!=i+1:
ans.append([1,i+1])
flip(a,0,i+1)
else:
ans.append([i+2,n])
flip(a,i+1,n)
Edit: Another pair of submissions
