#include <iostream>

using namespace std;

int suma(int n)

{

   int s=0;

   while(n>0)

   {s=s+n%10;

    n=n/10;

   }

return s;

}

int main()

{

   int n,v[100],i,j;

   cin>>n;

   for(i=1;i<=n;i++)

       cin>>v[i];

   for(i=1;i<n;i++){int s1=suma(v[i]);

       for(j=i+1;j<=n;j++){int s2=suma(v[j]);

           if(s1==s2) cout<<"("<<v[i]<<","<<v[j]<<")"<<" ";}}

   return 0;
