My issue

Exception in thread “main” java.util.NoSuchElementException
at java.base/java.util.Scanner.throwFor(Scanner.java:937)
at java.base/java.util.Scanner.next(Scanner.java:1594)
at java.base/java.util.Scanner.nextInt(Scanner.java:2258)
at java.base/java.util.Scanner.nextInt(Scanner.java:2212)
at Codechef.main(Main.java:16)
what does it mean

My code

/* package codechef; // don't place package name! */

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
	{
	    Scanner input=new Scanner(System.in);
	    int t,min,index,i,pass,students;
	    t=input.nextInt();
		while(t-->=0){
	    students=input.nextInt();
	    pass=input.nextInt();
	    int marks[]=new int[students];
	    for(i=0;i<students;i++){
	        marks[i]=input.nextInt();
	    }
	    Arrays.sort(marks);
	    index=students-pass;
	    min=marks[index];
	    min--;
	    System.out.println(min);
	    
	    
	}
	}
}

while loop’s condition should be t–>0 not t–>=0.
