int main() {
	// your code goes here
	int a[10];
	for(int i=0; i<10; i++){
	    cin>>a[i];
	    a[i]=a[i]%42;
	}
	sort(a, a+10);
	int count=0;
	for(int i=1; i<10; i++){

	}

@hp_68
u have to take 10 test cases as well.

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

int main() {
	// your code goes here
	int t;
	t=10;
	while(t--)
	{
	int a[10];
	for(int i=0; i<10; i++){
	    cin>>a[i];
	    a[i]=a[i]%42;
	}
	sort(a, a+10);
	int count=0;
	for(int i=1; i<10; i++){
	    if(a[i]==a[i-1]) count++;
	}
	cout<<10-count<<endl;
	}
	return 0;
}
