You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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'.

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?
Solution: 1
Why? 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: Speaker 1: Hey. Happy Thanksgiving!
Speaker 2: God, your hair sure is different!
Speaker 3: Yeah, we were just talking about that. I can't believe how stupid we used to look.
Speaker 1: So uh, where's Monica?
Speaker 4: She's upstairs. Monica! Come down! Everyone's here! Ross, Rachel, and the boy who hates Thanksgiving.
Speaker 5: Hi, Chandler.
Speaker 3: Oh my God!
Speaker 5: What-what's the matter? Is there, is there something on my dress?
Speaker 3: You just, you look so different! Terrific! That dress! That body!
Speaker 1: Dude!
Speaker 3: Sorry!
Speaker 4: Yes, yes Monica is thin. It's wonderful. But what we really want to hear about is Ross's new girlfriend.
Speaker 1: Oh mom! Okay, umm, her name is Carol. And she's really pretty. And smart. And uh, she's-she's on the lacrosse team and the golf team. Can you believe it? She plays for both teams!
Speaker 5: So Chandler, I guess I'll see you at dinner.
Speaker 2: Dude!
