thanks man

I also faced the same problem. I found out that if multiple scanners are instantiated , then the scanners take the whole input as the input for one single scanner.

Hope this helps!!!

now it gives me wrong answer even after successful execution…while it runs fine on bluej

thank you! it’s working…

this Code works well in my Laptop but giving runtime error(NZEC) while submitting solution. PLEASE HELP!!!
here is my code---->

import java.util.*;

public class Devu_Charu_Game {

public static void main(String args[]) {
 
       Scanner sc = new Scanner(System.in);
    if (sc.hasNext()) {
        int N = sc.nextInt();
        int M = sc.nextInt();
        int a[] = new int[N];
        for (int i = 0; i < N; i++) {
            a[i] = sc.nextInt();
        }

        int x[] = Get(a, N);
        for (int j = 0; j < M; j++) {
            char C = sc.next().charAt(0);
            int Q = sc.nextInt();
            char W = sc.next().charAt(0);
            int temp = 0;
            if (C == '>') {
                for (int i = 0; i < x.length; i++) {
                    if (x[i] > Q) {
                        temp++;
                    }
                }
            }

            if (C == '<') {
                for (int i = 0; i < x.length; i++) {
                    if (x[i] < Q) {
                        temp++;
                    }
                }
            }

            if (C == '=') {
                for (int i = 0; i < x.length; i++) {
                    if (x[i] == Q) {
                        temp++;
                    }
                }
            }
            if (W == 'D') {
                if (temp % 2 == 0) {
                    System.out.println("C");
                } else {
                    System.out.println(W);
                }
            }
            if (W == 'C') {
                if (temp % 2 == 0) {
                    System.out.println("D");
                } else {
                    System.out.println(W);
                }
            }

        }
    }


}

public static int[] Get(int a[], int N) {
    int na[] = new int[(N * (N + 1) / 2)];
    int x = 0;
    for (int i = 0; i < N; i++) {
        int max = a[i];
        for (int j = i; j < N; j++) {
            if (max >= a[j]) {
                na[x] = max;
                x++;
            }
            if (a[i] < a[j]) {
                max = a[j];
                na[x] = max;
                x++;
            }
        }
    }
   
    return na;
}

}

N can be as large as 10^6.

use try and catch block.

follow this part by

throws java.lang.Exception

58

try using this before you take any input:

if (!sc.hasNextInt())
System.exit(0);

you may also try:

throws java.lang.Exception

59

thanks buddy!!
but i am unable to use for(long i=0;i<N;i++) with array.
index value of array is long and stored values is int.
its showing lossy conversion from long to int for—> (x[i]<Q)

its like I have to use different data structure? :sweat_smile:

60

I have tried this!!
its giving ArrayIndexOutOfBoundException.

62

can you send the sepcifc solution link? it’ll help in assessing the problem.

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

/* 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
{
// your code goes here

Scanner s = new Scanner(System.in);
	

		int n = s.nextInt();
		
		int factorial = 1;

	
	for(int i = n; i>= 1; i--) {
	 
		 factorial = factorial * i;
	}
	
	System.out.println(factorial);

}

}

64

I use this try catch method but although this method removes NZEC , it does not provide any solution at all .Please resolve this issue someone.

65

Thanks, it’s working now. I guess java’s still tryna catch itself!

yeah both the answers are coming as wrong, it is very weird.
