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 input: 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 output: 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.
Q: Speaker 1: Hey, what did your agent say? 
Speaker 2: Yep, this kiss thing is definitely a problem, Mr. Beatty wants to see it again on Monday. Man, I gotta figure out what I'm doing wrong. Oh, okay, one of you girls come over here and kiss me. 
Speaker 3: What, forget it! 
Speaker 4: Yeah, right. 
Speaker 2: Come on, I need your help here. 
Speaker 5: All right. I'll do it, I kissed him before I can do it again. 
Speaker 2: You see this, this is a friend. 
Speaker 5: Uh-huh, let's go. Oh, wait I have gum. Okay. Good, very good, firm but tender. I'd recommend you to a friend. 
Speaker 2: Then I don't know what it is. What's the problem? 
Speaker 3: Joey, you know, maybe your just not used to kissing men, maybe you just tensed up a little, maybe that's what you need to work on. 
Speaker 2: Yeah, that makes sense. 
Speaker 6: Over my dead body! 
Speaker 1: And I'll be using his dead body as a shield.
