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'.

Let me give you an 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?
The answer to this example can be: 1
Here is why: 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.

OK. solve this:
Speaker 1: Alright. Just give me your wallets and there won't be a problem. 
Speaker 2: What? 
Speaker 1: I have a gun. 
Speaker 2: O-ok. Just relax, Phoebe, just stay calm. Oh my god, I can't find my wallet. 
Speaker 1: Alright, lady, now give me your purse! 
Speaker 3: No. 
Speaker 2: What do you mean "no"? I knew you'd be my death, Phoebe Buffay. 
Speaker 3: Lowell, is that you? 
Speaker 4: Phoebe? Oh my god! 
Speaker 3: Oh my god! 
Speaker 3: I'm sorry, Ross, this is my old friend Lowell from the streets. Lowell, Ross. 
Speaker 4: Ross, nice to meet you. 
Speaker 2: Yeah, a real pleasure. 
Speaker 3: Ah, it's been so long, so long. I can't believe you're still doing this! 
Speaker 4: Oh, I know, but I quit smoking! 
Speaker 3: Good for you! 
Speaker 4: So you look like you're doing really well! I guess you're mugging days are behind you? 
Speaker 3: Uh-huh. 
Speaker 2: Oh my god. Phoebe, you used to mug people? 
Speaker 3: Excuse me, Ross, old friends catching up...
