I am facing the same issue for the python program.
The Question link is: CSUB Problem - CodeChef
Please help me on how to solve this error.

t=input()
t=int(t)
i,counter,l,v=0,0,list(range(0,t)),list(range(0,t))
for i in range(0,t):
    l[i]=int(input())
    v[i]=int(input())

for i in range(0,t):
    counter=0
    while(v[i]>0):
        if v[i]%10==1:
            counter+=1
        v[i]=v[i]//10
        #print(v[i])
    ans= ((counter*(counter+1))//2)        
    print (ans)

Error I am getting

Traceback (most recent call last):
  File "./prog.py", line 1, in <module>
EOFError: EOF when reading a line

Dont know the reason but appently many python programmers are facing this issue
I would suggest switch to c++ or java

96

You need to come up with a better approach to solve it. The constraints on L and R are 1018. So recursion won’t work be it Python, C++ or Java.

97

For python 3 do I need to use raw_input() as well ?

98

NZEC error still unresolved. and the biggest problem is that you can’t check the output of your submission. I changed all reference of ‘input()’ (Python 3.6 code) to ‘sys.stdin.readline()’ but still the code is not working properly after submission. Works just fine for custom input.

No , python 3 doesn’t even support that.
and don’t worry about white spaces as int(input()) will take care of that.

The thing is always assign your variable in global by assigning None to them. (this was my case once)

But still on clicking the submit button it shows nzec error

getting NZEC for my code ,in python`https://www.codechef.com/submit/FLOW001]

This might be helpful to someone. I used Java and it gave me NZEC. Even after removing all the functions and just taking input, it was giving me the same error. Finally, I decided to just comment all lines and add one line at a time to check which line was giving me error.

It was: int[][] arr = new int[n][n]

Here, n can go up to 314159.

When I gave the same number in my local system and executed, it gave me:
Exception in thread “main” java.lang.OutOfMemoryError: Java heap space

I was trying to allocate memory for a very big matrix(n^2). This was a mistake I never thought I would make. This is so basic and might help who are struggling with it.

It’s still not working for me !
here’s my code :

T=int(input())
n=int(input())
for z in range(T) :
b=[]
a=list(input().split())
a=list(map(lambda x:int(x),a))
#print(a)
for i in range(len(a)) :
count=0
for m in range(0,i) :
if int(a[m]) % int(a[i])==0 :
count+=1
b.append(count)
print(max(b),)
it shows NZEC error in the first line itself

104

If you’re using Codechef IDE, you need to provide a custom input, or it won’t work. To submit the code, switch to non-IDE mode and then Submit.

Why am I getting this error on python3.6?

For python…

  1. if input demands accepting more than 1 input in a single line.

Then this won’t work…
p = int(input())
q = int(input())

Instead try,
p,q = map(int, input().strip().split())

  1. If code runs on your computer and problem is just while submitting.

Provide custom input in codechef ide or directly submit. Then it wont show NZEC.

		    int[] series=new int[n];
		    series[1]=1;
		    for(int j=2;j<n;j++){
		        series[j]=series[j-1]+series[j-2];

		    for(int j=0;j<n;j++){
		        series[j]%=10;
		    }
		    
		    while(series.length>1){
		        int[] derived=new int[series.length/2];
		        int c=0;
		        for(int k=1;k<series.length;k+=2){
		            derived[c++]=series[k];
		        }
		        series=new int[derived.length];
		        System.arraycopy(derived, 0, series, 0, derived.length);
		    }
		    System.out.println(series[0]);
		}
	}
}

When I am running this code, it runs absolutely fine. But, it shows a NZEC while submitting. Why?
