add return 0; at the end it will fix the run-time error
In java ,it’s showing NZEC error. WHY?
Any Hint?
In java , I’m getting NZEC error . why? any guess?
so many people getting WA despite being a simple problem and what it seems to be a correct solution. Something is fishy here

can anyone tell why my code gives runtime error sigsegv
#include
using namespace std;

while(t–){
int n,m;
cin>>n>>m;
int a[n+1]={0};
for(int i=0;i<m;i++){
int x;
cin>>x;
a[x] = 1;
}
int c=0,f=0;
int chef[n]={0},ass[n]={0};
for(int i=1,j=0,k=0;i<n+1;i++){
if(a[i]==0&&c==0){
chef[j]=i;
j++;
c=1;
f=0;
}
else if(a[i]==0&&f==0){
ass[k]=i;
k++;
f=1;
c=0;
}
}
for(int i=0;chef[i]!=0;i++)cout<<chef[i]<<" “;
cout<<endl;
for(int i=0;ass[i]!=0;i++)cout<<ass[i]<<” ";
cout<<endl;
}
return 0;
}
tho it gives ac for int chef[n+1],ass[n+1];
Can someone guide me where the issue lies. It works perfectly with the Sample I/O but fails to submit correclty.

Wrong answer, but there is no one to check the code on the server now…
Can anyone please post executed python code for this question? Because I’m getting run time error while trying to submit the question.
for _ in range(int(input())):
n, m = map(int, input().split())
s = list(map(int, input().split()))
l = []
for i in range(1, n+1):
l.append(i)
for p in s:
l.remove(p)
chef = []
assistant = []
for i in l:
if (l.index(i)+1)%2 == 0:
assistant.append(i)
else:
chef.append(i)
print(*chef, sep = ' ')
print(*assistant, sep = ' ')
Use Try catch. error Will be gone!!
I have solved the problem in c# .but i cannot submit the program as c# is not avaliable .i had drop a mail at bugs@codechef.com but have not received the response.

I can’t seem to find the mistake in this: -
# cook your dish here
try:
t = int(input())
while (t > 0):
secondLine = list(map(int, input().strip().split(' ')))
n = secondLine[0]
m = secondLine[1]
thirdLine = list(map(int, input().strip().split(' ')))
chef = []
assistant = []
for i in range(1, n + 1):
if i in thirdLine:
continue
if (len(chef) + len(assistant)) == (n - m):
break
if (len(chef) + len(assistant)) % 2 != 0:
assistant.append(i)
else:
chef.append(i)
t-=1
print(*chef)
if t == 0:
print(*assistant, end='')
else:
print(*assistant)
except:
pass
It keeps giving me runtime error and if I put try/except then it gives wrong answer. Can someone please help?
I would advise everyone to not waste their time on this problem.
Your solutions are all correct and this problem is very straight forward.
There is an error in the judge because the inputs have not been tested properly across all languages. It’s a very frequent problem in Codechef contests to get runtime errors - sometimes its extra spaces, sometimes its invalid characters, anything and everything not conforming to specified input format. I am just more let down that this happened in a cook-off problem and is still not rectified

I agree. This should be addressed. I solved the problem in 15 mins and then ended up wasting 1.5 hours to understand what went wrong and still couldn’t figure it out. My core language is Java but I am writing these in python to learn it and kept thinking what mistake I made in syntax after I realized that the logic is correct.

This code runs properly with custom inputs but it shows runtime error after submitting this

Can anyone please help me, what is the mistake in my code/logic.
Thanks.
u r working with default values when only declaring array(char jobs[n+1]).
try to assign while declaring the array
char jobs[n+1]={0}
