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?

Problem: Speaker 1: Okay, well, this is crazy. Can't seriously be talking about me taking one of your kids, can we? 
Speaker 2: No, of course we're not. 
Speaker 1: Insane. 
Speaker 2: I know. 
Speaker 1: Alice would never go for it, right? 
Speaker 2: Oh, I don't know, she's pretty tired, too, I think we've got her onboard. 
Speaker 1: Well, just you know, for argument's sake, you know, hypothetically. Which one would you be willing to give up? 
Speaker 2: Huh. 
Speaker 1: Frank Jr.Jr.? 
Speaker 2: Oh, you'd be getting a really good one. I mean, you know, he's really funny. Like, the other day he made up this joke. 
Speaker 1: Uh-huh. 
Speaker 2: What's green and says "hey, I'm a frog"? A talking frog! Oh, no, you can't have him, he's too funny. 
Speaker 1: Well, alright, that's fine. What about Leslie? 
Speaker 2: Oh, no, no. Not Leslie. No, she's, she's the only one that knows how to burp the alphabet. 
Speaker 1: Alright, so that leaves Chandler. 
Speaker 2: Oh, no, no, you can't have Chandler, no. No, no. She's my little genius. I got big hopes for her. She's gonna be a doctor or a realtor.. 
Speaker 1: Wow, Frank. I think we just ran out of kids. 
Speaker 2: Oh, I think you're right. Oh, wow. Phoebe, I don't think I can give one of them up. I mean, you know, they drive me crazy, but they're my babies. 
Speaker 1: I'm sorry, Frank. I didn't realise things were so bad. You know, I'll help out more. I can - I can babysit any time you want. You name the day, and I'll be there. 
Speaker 2: How about tomorrow? 
Speaker 1: Well, that's not good. But you know, I can move some stuff around, and I'll be there. You and Alice just take the whole day together. 
Speaker 2: You'd do that for us? 
Speaker 1: Are you kidding? That's what sisters are for. 
Speaker 2: Look at them! Aw. I love you so much. Oh crap, don't wake up, don't wake up!
