    is something wrong with test case 5

    HashSet<String> set=new HashSet<>(t);
        
        for(int i=0;i<t;i++){
            
            if(set.add((pair_left[i] + "#" + pair_right[i]))){
                
                System.out.println(set.size());
            }else{
                System.out.println(set.size());
            }
        }
