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: I don't think you had an open mind about the name Ruth. I mean, come on, little Ruthie Geller, how-how cute is that?
Speaker 2: Oh, oh my God! I can practically hear the mahjong tiles!
Speaker 3: Okay! All your tests look fine. Now, are you two interested in knowing the sex of the baby?
Speaker 1: Uh, no. No, we're not.
Speaker 2: But you have it right there in that file? You could tell us whether it's a boy or a girl? Dayton or Sandrine? Phoebe or Phoebo?
Speaker 3: That's right. But if you don't want to know...
Speaker 1: No, no, we want to wait, right?
Speaker 2: Right. Right.
Speaker 3: Oh, I'll be right back. And, uh, I know it's really not my place, but please don't name your child Phoebo.
Solution:
