Is it legal to ask questions related to codeforces problem set (practice) on codechef?
As both are coders platforms! Initially i started coding for the first time at codechef but was scared so someone suggested me solving on codeforces and i feel more comfortable there because you can see your failing test cases there.
I have a Question. If you are topmost coder of Codechef but you have 0 karmapoint then can you ask question or Not ? Is it fair to decide only according to karmapoints and not your rank and rating?
First off thanks for doing this, because I have questions. How do I get better at understanding the problems? I am doing beginner and just read the problem and want to claw my eyes out because I have no clue what they are asking. Is there a trick to getting better at it?

Is it because it’s a practice contest??

While using Codechef IDE, I noticed a bug. If a line is selected and Ctrl + / is pressed then, in general for other languages (I checked for C, C++ 6.3, C++ 17, PYTH, PYTH 3.5) the lines get commented out. But for PYPY, just a // is put before the lines, which is definitely not commenting out in case of PYPY.
Can you please check this and inform @admin if it is truly a bug (in case she does not notice).
Thanks.

Codechef Newbie here,
Below is my code for the recent Cookoff 89. Problem Football Match. It passes the example case, but then gives Wrong Answer after I submit. What is the error in my code?
n = int(input())
team1 = ""
team1count = 0
team2 = ""
team2count = 0
scoreArr = []
for x in range(n):
testcaseNumber = int(input())
for y in range(testcaseNumber):
scoreArr.append(input())
for z in scoreArr:
if team1 != "" and team2 != "":
continue
elif team1 == "":
team1 = z
team1count = scoreArr.count(z)
elif team2 == "":
team2 = z
team2count = scoreArr.count(z)
if team1count == team2count:
print("Draw")
elif team1count > team2count:
print(team1)
else:
print(team2)
team1 = ""
team2 = ""
team1count = 0
team2count = 0
scoreArr = []
Thanks so much!
Where can I ask competitive programming questions?
Sometimes I am not able to understand problems or editorials or want to know some other way to solve the problem.Stack overflow community downvotes these type of questions.So is there any other site where I can post my queries and get answers in reasonable time?
