How to find NZEC error ??

Hi! please tell me what is NZEC error, how to find it inside the code and how to prevent it ?
How do codechef encounter NZEC errors, do they use any software ??

can u post ur source code for which u get this NZEC error??
then its easy for us to figure out

Usually, returning non-zero values from main() will cause this error. It helps telling crash from WA (Wrong Answer) with interpreted languages. Typically this would happen if you omit a return 0; from main() in C. For interpreted languages or Java/C++, this could happen if your program threw an exception which was not caught (e.g. Trying to allocate too much memory in a vector).

I am new to python and programming after all…
The program runs correctly but gives NZEC error during submission plz check this code… Its the solution to first question in Code Chef >> Practice>> Easy

n = long(raw_input('N = '))
m = long(raw_input('M = '))
k = long(raw_input('K = '))
#print n #####used for testing puposes
#print m
#print k
dict1 = {}
arr = []
arrc = []
ctr = 0

for i in range(n):
temp = raw_input("element %d: " %i)
temp = int(temp)
arr.append(temp)

#print arr ############ these are used for testing can be omitted

for i in range(n-1):
arrc = arr[:]
sums = 0
for j in range(i+1,n):
while(arrc* <= m and arrc[j] <= m):
arrc*+=k
arrc[j]+=k
for j in range(n):
sums+=arrc[j]

print arrc ######### these too

print sums ######### —do----

dict1[sums] = sums      

#print dict1 #for testing purposes

ctr = (dict1.sizeof()/124) % 1000000007

print "Ans= ",ctr

How can I remove NZEC error from the following code:-

import java.util.Scanner;

class holes {

public static void main(String args[]){

Can anybody help with NZEC in question FIRESC http://www.codechef.com/problems/FIRESC/ .

Here is my solution http://www.codechef.com/viewsolution/7268210

Runtime Error(NZEC)
t=int(input())
a=[]
b=[]
c=[]
if t>=1 and t<=1000 :
for i in range(t):
a.append(int(input()))
b.append(int(input()))
if a*>=1 and a*<=10000 and b*>=1 and b*<=10000 :
c.append(a*+b*)
for i in range(t):
print(c*)
How can I solve this in codechef ?

can anyone tell me about the runtime error caused in my written code----

Can Anyone tell me about my NZEC error?
My code is…

#include<stdio.h>
/*gcc C,Turbo C*/
float main()
{
int x,y=120;
float r;
scanf("%d",&x);
if (x%5!=0)
{
printf("Incorrect widrwal");
}
else if (x>y)
{
printf("Insufficient Funds");
}
else if(x%5==0)
{
r=(120-x)-0.50;
printf("Puja's account balance is %f",r);
}
return 0;
}

I am getting this error. I have tried this code for many sample input. However, it is showing NZEC error when i try submitting the code.

I am facing NZEC runtime error in this code.. what wrong am i doing??

t=int(raw_input()) while(t>0): c=int(input()) d=int(input()) l=int(input()) if l%4==0: l1=l/4 if l1<= c+d: if c<=2d and l1>=d: print "yes " elif c>2d and l1>= c+d-2*d: print "yes " else: print "no " else: print "no " else: print "no " t-=1

@adicodechef

I highly suspect that the error is due to missing return statement and “main()”

Change it to “int main()” and add a “return 0;” in end of program.
