Why do I get an NZEC?

I’ve searched through forums and similar code but I’m still getting NZEC. I suspect it could be something with input/output or an index going out of bounds on an array. Any suggestions? CodeChef: Practical coding for everyone

why NZEC in java code ??? any help please

18

My python code is encountering the NZEC error.

How will my code be able to receive multiple input from single line, if those inputs are in the form of an array.

Please tell me what to change in this piece of code, to be able to accept an array of inputs from the user.

pies=[]

for j in range(0,np):

pies.append(int(raw_input()))

This is the code to receive input if they are printed on consecutive lines.
The problem is that all the inputs are being entered on the same line, but how do i receive the array of inputs from the same line?

My all programs give NZEC error when submitting when using C#.
All the programs work perfectly with IDE. Any help ?
It’s a shame there’s no support for this problem.

Using Python here. I have used raw_input(), split() , etc. and all that has been suggested here. Still, I am getting this error. Any ideas why ?

public class SumOfDigits{
public static void main(String args[]){
Scanner sc= new Scanner(System.in);
System.out.println(“Enter a number”);
int number = sc.nextInt();
int sum = 0;
int input = number;
while(input!=0){
int x = number%10;
sum+=x;
input=number/10;
}
System.out.println(sum);
sc.close();
}
}

What is wrong with my code? It shows NZEC runtime error.

24

for z in range(int(raw_input())):

na = raw_input()

seq = str(raw_input())

na = raw_input()

seqf = str(raw_input())

flag = 'Yes'

for i in seqf:

    if i not in seq:

        flag = 'No'

print (flag)

why am I getting NZEC error in this one?

25

what is error in this code :

m=n=k=t=0
res=[]
inp = ""


t=int(input())
while t:
	inp=raw_input()
	m=int(inp[0])
	n=int(inp[2])
	k=int(inp[4])
	while k:
		if m>n :
			n+=1
			k-=1
		elif n>m:
			m+=1
			k-=1
		else:
			break
	res.append(abs(m-n))
	t-=1

for out in res:
	print out

My python code is running good in my laptop but when submitted in codechef it is throwing run time NZEC error. My code is:

n = int(raw_input())
a = []
while n>0:
	p,q = map(int, raw_input().split())
	c = max(p,q)
	a.append(c**2)
	n = n-1
d = sum(a)
e = int(d**(.5))
print e

Here is my java code.
Why do I get an NZEC?

import java.util.Scanner;

public class Main{
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
String lines = reader.nextLine();
String[] strs = lines.trim().split("\s+");
int a[] = new int[50];
for (int i = 0; i < 2; i++) {
a[i] = Integer.parseInt(strs[i]);
}
if ((a[0] > a[1] - 0.5) || (a[0] % 5 != 0)) {
System.out.println(a[1]);
} else {
System.out.println(a[1] - (a[0] + 0.5));
}

}

}

In my case in java code, multiple things were there:

-the code had an error which was causing arrayOutOfBoundException for certain test cases, which were not given in the sample test cases. Removing that bug did half the work;

-BUT MORE IMPORTANTLY, I was using eclipse, which recommends giving package name, so my code looked like:

	package main;
	
	import java.io.IOException;
	
	public class Main {
             --actual implementation
   }

here the problem is with the first line, you can not use package name. So removing the first line i.e. package main; line caused the code to run successfully.

-in general NZEC is a very common error, if you have any bug in your code, then NZEC error could be thrown,

I’m using input() in python3, pretty sure raw_input() was decprated in python3 so does that means I’m always gonna get NZEC on codechef??
