My issue

time limit is exceeding.

My code

import java.util.*;
import java.lang.*;
import java.io.*;
import java.util.Arrays;
class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		// your code goes here
		Scanner r = new Scanner(System.in);
		int t = r.nextInt();
		while(t-->0 ){
		    int n = r.nextInt();
		    int[] a = new int[n];
		    for(int i = 0 ; i <n; i++) {
		        a[i] = r.nextInt();
		    }
		    int[] b = new int[n];
		    for (int i = 0 ; i < n; i++) {
		        b[i] = 0;
		        for (int j = 0 ; j <n; j++) {
		            if (a[j] == a[i]) b[i]++;
		        }
		    }
		    Arrays.sort(b);
		    int ans = n- b[n-1];
		    System.out.println(ans);
		    
		    
		}

	}
}

@samraddh773
plzz refre my c++ code for better understanding of the logic

#include <iostream>
#include<algorithm>
using namespace std;

int main() {
	// your code goes here
		int t,i;
	cin>>t;
	while(t--)
	{
	    int n;
	    cin>>n;
	    int a[n];
	    for(i=0;i<n;i++)
	    {
	        cin>>a[i];
	    }
	    int count=1;
	    
	    sort(a,a+n);
	    int ans=0;
	    
	    for(i=1;i<n;i++){
	        if(a[i]==a[i-1])
	        {
	        count++;
	        }
	        else
	        {
	            ans=max(ans,count);
	            count=1;
	        }
	    }
	    ans=max(ans,count);
	    cout<<n-ans<<endl;
	    
	}
	return 0;
}
