While submitting the Solution I am getting Runtime Error(NZEC)

import java.util.;

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
{
Scanner sc=new Scanner(System.in);
int t=sc.nextInt();
while(t!=0){
double ans=1;
double k1=sc.nextInt();
double k2=sc.nextInt();

	    double k3=sc.nextInt();
	    double v=sc.nextInt();
	    
	    ans=100/(k1*k2*k3*v);
	    
	    if(ans<9.576){
	        System.out.println("Yes");
	    }else{
	        System.out.println("No");
	    }
      t--;
	}
}

}

Please format your code.

Reason :- You are using Scanner for taking input , which is slowest but easiest way to take input in java.
I would recommend you to use Reader class(much faster way to take input in java) defined in given below link to doc. :
