I got a system message about my solution (89664275)

w,h,sx,sy = map(int,input().split())

for x in range(sx, w+1):
for y in range(sy, h+1):
print(x,y)
for y in range(1, sy):
print(x,y)
sy = y
for x in range(1, sx):
for y in range(sy, h+1):
print(x,y)
for y in range(1, sy):
print(x,y)
sy = y

n,m,x,y=map(int,input().split())
for yy in range(y,m+1):
for xx in range(x,n+1):
print(xx,yy)
for xx in range(1,x):
print(xx,yy)
x=xx
for yy in range(1,y):
for xx in range(x,n+1):
print(xx,yy)
for xx in range(1,x):
print(xx,yy)
x=xx

Clearly it does, but it has all to do with the task being trivial and the approach taken being one of the least resistance ones (and this being python where you don't have a gazillion lines of template to obscure any potential similarities).

I guess to make it clear, I do not use any form of online IDE. All code I write is written locally on my machine, and has not left my machine other than through uploading my submission to the contest. So any similarities should be completely coincidental.

I choose to code some tasks in python just because of how clean and nice it is. I use templates for c++ because they are actually needed there.I see now that the code is actually not the same. We have transposed outputs. He does row by row and I do column by column. In any case this should be dealt with. I'm not sure if I am impacted negatively at all because of this, but it's unfair to antonkasko who got skipped (while seemingly doing a pretty good contest).To my eyes it seems like a serious account. Mixed python and c++ usage (so not surprising to see the guy write python code for the light tasks). It's hard to write this (quite obvious) approach much differently in python without introducing unneeded cruft.

 » 5 weeks ago, # |   +3 I think for A problems, the solutions are usually extremely short (and thus, quite likely to be similar). I don't think Codeforces should ever call it plagiarism when the code is less than a certain number of lines/characters.
