Here is my data structure

![enter image description here](https://i.stack.imgur.com/e2rnD.png)

So the 0 is the 1st day of the month and so on. So basically it's looping but I have no idea what should I do. I need an idea where to start or what should I do.

What I want my output is 

So if its the first day of the month so thats 0 on the child the price will be 1 and the next day will be 2

This is my code 

```
    mRef3 = mRef.child(key).child("promos").child("regular").child(ym).child("price").child("guest1/0");

 mRef3.addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                    String price = dataSnapshot.getKey()+": "+dataSnapshot.getValue();
                    holder.rPrice.setText("FROM " + getString(R.string.currency) + " " + price + " per night ");
                }

                @Override
                public void onCancelled(@NonNull DatabaseError databaseError) {

                }
            });

```

CURRENT OUTPUT: 
FROM USD 0:1 per night
