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¦

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 :-

See lines 17,18,23,26,40,51.This is a clear indication of plagiarism .
Also his remaining code matches exactly with others

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!

@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 .

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
