import java.util. *;
import java.lang. *;
import java.io. *;

class Test {
public static void main (String[] args) {
Scanner sc = new Scanner(System.in);

int t = sc.nextInt();
int[] arr = new int[t];
int n = 0, rem = 0, ans = 0;
for(int i = 0; i < t; i++){
	n = sc.nextInt();
	ans = 0;
	while(n != 0){
		rem = n % 10;
		ans = (ans * 10) + rem;
		n /= 10;
	}
	arr[i] = ans;
}
for(int i = 0; i < t; i++){
	System.out.println(arr[i]);
}

sc.close();

}
}

Why this code shows NZEC on codechef. But, it runs perfectly on my system

don’t run the program directly, use the custom test case add custom input from the question then run.
Codechef has some problem with direct run in java.
or submit your code, its correct.
