post your code using “code” html tag or link your code.

use this

int t = 0;
if(scanner.hasNextInt()) t=input.nextInt();

when submitting your code, remember the space provided to you. It usually happens when your program uses more stack memory than provided i.e. stack overflow, try submitting your code in c/c++ . it will reduce your space requirements, i also tried this and it is actually affective

i also got NZEC error while submitting solution in java,error is not coming with custom input.
i tried as you said like below
/* package codechef; // don’t place package name! */

import java.util.;
import java.lang.
;
import java.io.;
import java.util.stream.
;

/* Name of the class has to be “Main” only if the class is public. */
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
//Scanner sc = new Scanner(System.in);
try{
String T = br.readLine();
String T2 = br.readLine();
System.out.println(T+" "+T2);
}catch(Exception e){
e.printStackTrace();}
}
}
i get output as
null null
, is this mean no input is provided for non custom run ?
can you please help

Yes :slight_smile:

class MAIN{

public static void main(String[] args){
	try{
	MAXSPSUM m=new MAXSPSUM();
	m.read();
	m.assign()		;
	m.sp_sum();
}

catch(Exception e){System.out.println((e));
return ;
}
}}

class MAXSPSUM{
Scanner sc=new Scanner(System.in);
long k,s;
int n;
int p;
long[] a;
long[] prod;
long[] sum;
public void read(){

	n=sc.nextInt()	;
	k=sc.nextLong();
	s=sc.nextLong();
	this.p=(int)Math.pow(2,n);
	prod=new long[p];
	sum=new long[p];
	a=new long[n];
	for(int i=0;i<n;i++)
		a[i]=sc.nextInt();
}	


public void assign(){

	Arrays.fill(sum,0);
	Arrays.fill(prod,0);
	int i,j,l=0,k;
	for(k=0;k<n;k++){
		for(j=0;j<n;j++){
			for(i=k;i<n-j;i++)	{

				sum[l]=sum[l]+a[i];
				prod[l]=prod[l]*a[i];

			}



			l++;
		}	

	}}

public void sp_sum(){	
	int i;
	long prev=0,max=0;
	for(i=0;i<p;i++){

		prod[i]=prime(i);
		prev=(sum[i])*(k-(prod[i])*s);

		if(prev>max)
			max=prev;

	}
	System.out. println(max);
}	

int prime(int i)		{
	int count=0;	
	for(int j=1;j<=prod[i];j++){
		if(prod[i]%j==0&&Isprime(j))
			count++;
	}

	return count;		
}
boolean Isprime(int i){
	int count=0;
	for(int j=1;j<=i;j++){
		if(i%j==0)
			count++;}
	if(count==2)
		return true;
	else return false;


}

What wrong in this code why it is showing nzec error

I found this the hard way… by default… codechef doesn’t give any test inputs. So, i think, we need to click “custon input”, enter our custom input and then run it. Otherwise, we get this NZEC error

using System;

public class Test
{
public static void Main()
{
int n = int.Parse(Console.ReadLine());
for (int i = 0; i < n; i++)
{
int x = int.Parse(Console.ReadLine());
int count = 0;
bool isEntered = false;
int[] arr = new int[x];
string value = Console.ReadLine();
for (int j = 0; j < x; j++)
{
arr[j] = int.Parse(value.Split(’ ')[j]);
}
for (int j = 0; j < arr.Length; j++)
{
if (arr[j] == 1)
{
if (count == 0)
{
count++;
isEntered = true;
}
else if (count < 6)
{
isEntered = false;
Console.WriteLine(“NO”);
break;
}
else if(count>=6)
{
Console.WriteLine(“YES”);
break;
}

                }
                else if (isEntered == true)
                {
                    count++;
                }
            }

        }
}

}

This code is showing NZEC problem… Coding in C#… Can anyone help me with this

You need to click on the checkbox mentioning “Custom Input”

Provide the inputs, and the program will work.

//This is for Java

Why is try catch required in java code to get rid of NZEC?
What is cause of this error NZEC?

public static void main (String[] args) throws java.lang.Exception
{
// your code goes here
try{
Scanner sc = new Scanner(System.in);
int test_cases;
int temp = 0;
final int FIX = 10;
int number;
test_cases = sc.nextInt();
while(test_cases>0)
{
number = sc.nextInt();
while(number>0)
{
temp = temp*FIX + number%FIX;
number /= FIX;
}
number = temp;
temp = 0;
System.out.println(number);
}
test_cases --;
}catch(Exception e){
return;
}
}

In this code, if i remove try catch, it gives Nzec error. Why ?

Use try and catch block

I encountered the same error. This error is encountered while the compiler is trying to take input.
Try this condition while taking input:-
if( scanner.hasNext()) {
input = scanner.nextInt();
};

Thanks man!

works fine on laptop but NZEC here.help.

Thanks it helped me alot

for _ in range(int(input())):
    n=int(input())
    l=set(map(int,input().strip().split()))
    print(len(l))

use below code to get rid from noSuchElementException…

if(sc.hasNextInt()){
int cases = sc.nextInt();
}
