I just also had an NZEC
at XENTASK using python 3. I used python 3’s input()
, selecting pypy
as programming language and #! python3
as first code line. This worked before at other tasks, but seems to be the problem at XENTASK. Solved it by simply selecting py 3
as programming language, and it worked fine.
So if you use python 3, that might do the trick.
I am getting NZEC error for this code:
/* package whatever; // don’t place package name! */
import java.util.;
import java.lang.;
import java.io.*;
/* Name of the class has to be “Main” only if the class is public. */
class Ideone
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner sc = new Scanner(System.in);
int t,n ;
t = sc.nextInt();
int i;
while(t-->0)
{
n = sc.nextInt();
int c = 1;
while(n!=1){
for(i=n-1;i>=1;i--)
{
if(n%i==0)
{
c++;
n = n - i;
break;
}
}
}
if(c%2==0){
System.out.println("ROHIT");
}
else{
System.out.println("VISHAL");
}
}
}
}
how do i solve this?
it works fine on ideone but while submitting on codechef i get this runtime error…
Please help me…
Can anyone check why am I getting NZEC in java… I have done everything possible after searching this whole Forum…

I am getting NZEC error pleaSE help me .
import java.util.Scanner;
public class Main {
public static void main(String[] args)
{
int c=calculate();
System.out.println(c);
}
public static int calculate()
{
int count=0;
Scanner inp=new Scanner(System.in);
System.out.println("Enter No. of time input take:\t ");
int n=inp.nextByte();
int a[]=new int[n];
System.out.println("All input must be divisible \t "); //k<10pow7
int k=inp.nextByte();
System.out.println("Enter values:");
for(int i=0;i<n;i++) {
a[i] = inp.nextInt();
if (a[i] % k == 0)
count++;
}
return count;
}
}
I was solving this problem SUMTRIAN( SUMTRIAN Problem - CodeChef ) and was getting this error with Python. I was getting input using raw_input() which was coupled with split(’ ') to get a list. This is how I was taking input and converting it into a list of integers : lst = map(int, list(raw_input().split(’ ')))
Solution to this error:
Change the code to : lst = map(int, list(raw_input().strip().split(’ ')))
strip() removes any unnecessary blank spaces in the input and this removed the NZEC error.
guys, please upvote me. i am new here. nad not able to ask question
you should probably return a 0 value
by taking int main() as the function in c
For the python users, you can refer to this discussion NZEC error in Python - Stack Overflow…
Hope it helps…!
For python use the following link.
Some python specific debugging NZEC:
If the issue is due to leading or trailing spaces any of the below should work for Python:-
- input().strip().split()
- input().strip().split(’ ')
- raw_input().strip().split()
- raw_input().strip().split(’ ')
If not there might be some other issue -
https://discuss.codechef.com/questions/72153/tutorial-how-to-debug-an-nzec-error
Common exceptions are
- LookupError (IndexError, KeyError)
- ArithmeticError (FloatingPointError, OverflowError, ZeroDivisionError)
The last thread is not python specific but the idea is great. I faced the issue currently in python so added these for common good.
I was getting same for a question in Python 2, try switching to input() and submit in Python 3. It worked for me.
My code is executing fine on my laptop but give NZEC error on codechef .Please can anyone tell me what’s wrong with it.
import java.util.Scanner;
public class Main {
static int max, p;
public static void main(String[] args) {
Scanner inp = new Scanner(System.in);
long n = inp.nextInt();
int A[] = new int[1000];
int B[] = new int[1000];
int i, j;
int lead;
for (i = 0; i < n; i++) {
A[i] = inp.nextInt();
B[i] = inp.nextInt();
}
for (i = 0; i < n; i++) {
if (A[i] > B[i]) {
lead = A[i] - B[i];
if (lead > max) {
max= lead;
p = 1;
}
}
else {
lead = B[i] - A[i];
if (lead > max) {
max = lead;
p = 2;
}
}
}
System.out.println(p+ " " + max);
}
}
my code is running fine in my laptop but getting nzec in codechef . iam using java and i have used bufferedreader class and scanner class both but iam still getting nzec in both cases
@codehardy can you please mention for which question you have write this code as you have created array A and B of size 1000 elements , which may be insufficient according to the constraints of the question.
Hello please, I am struggling with it too
package bytelandian;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;
class Bytelandian {
Map<Long, Long> alreadyComputed = new HashMap<>();
Long compute(Long n) {
if (n < 12) {
return n;
}
if (alreadyComputed.containsKey(n)) {
return alreadyComputed.get(n);
}
Long tmp = compute(n / 2) + compute(n / 3) + compute(n / 4);
if (tmp < n) {
tmp = n;
}
alreadyComputed.put(n, tmp);
// System.out.println(alreadyComputed + "");
return tmp;
}
public static void main(String[] args) throws Exception {
Bytelandian b1 = new Bytelandian();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String line;
while (!(line = br.readLine()).equals("")) {
System.out.println(b1.compute(Long.parseLong(line)));
}
}
}
example submission:

it says 4468M mem, but it seems impossible to me
please help, I would like to complete challenges, but error after error occurs when I would like to check my work
If you are using java then remove the package declaration to fix the NZEC error.
why i am getting nzec error while i am using javascript

This is solution of a question ,it is running perfectly on my laptop but giving an NZEC error on codechef.
Anyone please help.Help me in knowing my mistakes.
