Given the task definition, example input & output, solve the new input case.
You are given a dialog between 2 or more individuals. You need to generate the number of the speaker (e.g. 1 for Speaker 1) who had the most lines in the dialog. If there is a tie, output the answer '0'.
Example: Speaker 1: What do you think we should do for our 10th wedding anniversary?
Speaker 2: Hm, how about we take a vacation? Somewhere sandy and warm.
Speaker 1: Well, if we're going to go out of the country, you need to be sure to renew your passport. It expired over a year ago!
Speaker 2: How about we get something expensive instead of travelling. We could get a new car.
Speaker 1: Is this your way of telling me that you want me to buy you a car?
Output: 1
In this dialog, there are 5 lines of speech. Three of them belong to Speaker 1 and two of them belong to Speaker 2. Therefore, Speaker 1 has the most lines in the dialog.

New input case for you: Speaker 1: Joey, now that you're okay with the house, do you wanna go see your room?
Speaker 2: What? I get my own room?
Speaker 3: You don't think we'd buy a house and not have a Joey room do you?
Speaker 2: Oh my God! Oh! Hey, can I have an aquarium? And a sex swing?
Speaker 3,
Speaker 1: No!
Speaker 2: Why not? I'll keep the tank clean.
Output:
2
