Detailed Instructions: 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'.
See one example below:
Problem: 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
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: Pheebs, how's it going?
Speaker 2: I'm doing okay. I think it's going well. Do you think they're having fun? Am I talking too fast?
Speaker 1: Nope, sound like me. Pheebs, it's going great. Look at Chandler with little baby girl Chandler.
Speaker 3: Little baby girl Chandler, where I have heard that before? Oh right, Coach Ruben. Do you know what Pheebs? When you're done over there, we kinda have a situation over here too.
Speaker 2: Na-uh, no, we are all responsible for our own babies.
Speaker 3: See that's where I think that you're wrong. We've been playing these babies man for man; we should really be playing a zone defense.
Speaker 1: What do you mean?
Speaker 3: I just think that things would go a lot smoother if we each have our own zone. Phoebe, you can be in charge of wiping. And y'know Mon, you can be in charge of diapering and I can be in charge of looking how cute they are when they put their hands around...
Speaker 2: That sounds really great, but maybe you should be in charge of wiping.
Speaker 3: Okay, I'm a rookie. I should not be in the end zone.
