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: Oh my gosh! Rachel, honey.. are you okay? Where-where's Paolo?
Speaker 2: Rome. Jerk missed his flight.
Speaker 3: And then... your face is bloated?
Speaker 2: No. Okay. I was at the airport, getting into a cab, when this woman- this blonde planet with a pocketbook- starts yelling at me. Something about how it was her cab first. And then the next thing I know she just starts- starts pulling me out by my hair! So I'm blowing my attack whistle thingy and three more cabs show up, and as I'm going to get into a cab she tackles me. And I hit my head on the kerb and cut my lip on my whistle...oh...everybody having fun at the party? Are people eating my dip?
Solution: 2
