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: What are you guys gonna do?
Speaker 2: Well, I guess we just find a divorce lawyer?
Speaker 3: Well, I think, I think, Ross already has one. Now, this one's free, right? Because you paid for the first two, so the third one's free.
Speaker 4: Laugh it up, but the joke's on you. Because we don't need to get divorced, okay? We we're just gonna get an annulment.
Speaker 5: An annulment? Ross! I don't think surgery's the answer here.
Speaker 6: Oh-oh, that's your thing.
Speaker 4: What?
Speaker 6: You're thing. You're thing. Y'know? You're the guy who gets divorced.
Speaker 7: Oh yeah!
Speaker 4: No-no, that's-that's not my thing! I do not love getting divorced!
Speaker 6: Yes you do! This is your third divorce! You love divorce so much you're probably gonna marry it! Then it won't work out and you're gonna have to divorce it, divorcing guy. I'm so drunk.
