Have corrected your code just typing mistake.

``````/* 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 kb  = new Scanner(System.in);
int t = kb.nextInt();
while(t-->0)
{
int n = kb.nextInt();
int a [] = new int[n];
for(int i=0;i<n;i++)
{
a[i] = kb.nextInt();
}
Arrays.sort(a);
int Mcount = 0;

for(int i = 0;i<n;i++)
{
int c = 0;
for(int j=0;j<n;j++)
{
if(a[i] == a[j])
{

}
}
if(c>Mcount)
