@vedantgangrade
The implementation is not right.
U have to do it like this

#include <bits/stdc++.h>
using namespace std;

int main() {
	// your code goes here
	long long int n;
	cin>>n;
	long long int cnt=0;
	vector<long long int> a(n);
	map<long long int ,long long int> mp;
	for(int i=0;i<n;i++)
	{
	    cin>>a[i];
	    if(a[i]%6==0&&a[i]%5!=0)
	    {
	        mp[a[i]]++;
	    }
	}
	cout<<mp.size();
	return 0;
}
