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'.
One 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?
Solution is here: 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.

Now, solve this: Speaker 1: This is my father, Paul Stevens. Dad, this is Ross Geller. 
Speaker 2: It-it's great to meet you Paul. 
Speaker 3: I usually prefer Elizabeth's boyfriends to address me as Mr. Stevens. 
Speaker 2: Of course, of course, Mr. Stevens. 
Speaker 3: So Ross, what your problem? 
Speaker 2: Eh-wh-Excuse me? 
Speaker 3: Why can't you get a girlfriend your own age? 
Speaker 2: That's funny. Umm.... It's not funny. 
Speaker 3: I don't like you going out with my daughter Ross. 
Speaker 2: Okay. I can, I can see that. Umm, but I think if you give me umm, one chance I can, I can change your mind. 
Speaker 3: Okay. 
Speaker 2: What? 
Speaker 3: Okay. I'll give you one chance to change my mind. You got one minute. 
Speaker 1: Daddy! 
Speaker 3: Fine! Two minutes. Go. 
Speaker 2: This is-you- 
Speaker 3: 1 minute 50 seconds. 
Speaker 2: Okay, umm I want you to know that I have never done anything like this before. I mean, I mean I've been in um, relationships in general, uh but I have never done it with a student-I mean I not-not it! I mean, I mean I don't-We haven't done it. Uh, I mean, I mean, we've-we've-we've done stuff. Okay, okay, a joke, a joke-lighten the mood. Umm, two guys go into a bar. One of them is Irish. 
Speaker 3: I'm Irish. 
Speaker 2: And the Irish guy wins the joke!
