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?
Example solution: 1
Example explanation: 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.

Problem: Speaker 1: This is contestant number sixteen, Rebecca...
Speaker 2: Hey.
Speaker 3: Oh Phoebe, listen. Well, I think we gotta go. This place is really freaking me out. I've been watching this guy over there, I don't think he came with a kid!
Speaker 2: We can't leave now! There was this one baby, Haley, who was favourite to win and she got croup, so she had to stay home! This competition just blew wide open, folks!
Speaker 3: Phoebe, I think... It's just too weird, I just saw a one year old running around with pantyhose on!
Speaker 2: Oh, I know, we should have been more prepared. It's okay. Now, the way I see it, our real competition now is Cameron. Oh my God, they just took her sweater off. Look at those arms! Hello Michelin Man.
Speaker 3: Oh, Phoebe! Come on! You know what, it's already three o'clock and they haven't even gotten to Emma's group yet. We gotta go, we got dinner!
Speaker 2: But Emma's got what it takes, she could go all the way!
Speaker 3: Phoebe, you have to calm down.
Speaker 2: Okay. Rachel, the hottest babies in the Tri-State Area are in this room right now! I overheard one of the judges say that not one of them holds a candle to Emma!
Speaker 3: Really?
Speaker 2: Yeah!
Speaker 3: You heard them say that?
Speaker 2: Yeah!
Speaker 3: All right, okay. Alright, let's give to these babies something to cry about!
Speaker 2: Good! Oh yay! Let's get down to business! Emma needs some makeup!
Speaker 3: No, what?
Speaker 2: Well, she's gonna look all washed out next to the other contestants!
Speaker 3: No Phoebe, I am not letting you put makeup on my baby!
Speaker 2: Why not!
Speaker 3: Because I already did!
