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: Hello. Oh! It's you. Just ah, just one-one sec. I am going to take this call. When I continue, I hope that there will appear on stage this magical thing that in the theatre we call, committing to the moment!
Speaker 2: That guy's like a cartoon. What do you see in him anyway?
Speaker 3: He happens to be brilliant. Which is more than I can say for that sweater you're dating.
Speaker 2: Hey, I'm not interested in her sweater! It's what's underneath her sweater that counts. And besides, since ah, since when do you care who I'm going out with?
Speaker 3: I don't care. Why, do you want me to care?
Speaker 2: Do you want me to want you to care?
Speaker 3: Do you?
Speaker 2: What?
Speaker 1: Okay, I'm afraid to say this, but let's pick it up where we left off.
Speaker 2: Come on baby, don't go. Please? What do you say?
Speaker 3: I've got no reason to stay.
Speaker 1: Stop!! Stop it! You must stop! You are bad actors! This is a terrible play! I'll see you in the morning.
Speaker 3: I can't believe we go on in, in a week.
Speaker 2: Hey, it's gonna be all right.
Speaker 4: Hey! So since we're getting off early, do you want to go and paint mugs?
Speaker 2: What?
Speaker 4: You know! At the place I told you about last night?
Speaker 2: Oh, yeah, with the mug painting. Yeah. I was so listening to that. But ah, y'know what, I think I kinda need to work on my stuff tonight.
Speaker 4: Oh, okay.
Speaker 2: Okay.
Speaker 4: I'll see you tomorrow.
Speaker 2: Okay.
