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: Hi.
Speaker 2: Hi.
Speaker 1: I don't know why I'm here.
Speaker 2: I didn't ask. You wanna come in?
Speaker 1: I don't know.
Speaker 2: Oh, okay. Well, I'll just leave the door open and go sit on the couch.
Speaker 1: Chandler is such an idiot!
Speaker 2: Drink?
Speaker 1: Yeah, I'll have a scotch...
Speaker 2: ...on the rocks with a twist? I remember.
Speaker 1: Still smoking cigars?
Speaker 2: Uh, no! No! That's...art! If it bothers you I can put my art out.
Speaker 1: No that's, that's okay.
Speaker 2: So Monica let me ask you a question. Y'know, since we broke up do you ever, think about me?
Speaker 1: Uh yeah, I-I actually I thought about you a couple months ago.
Speaker 2: Oh really?
Speaker 1: Yeah but it was because I-I had an eye exam and I don't like my new eye doctor.
Speaker 2: Who is it?
Speaker 1: Edward Nevski?
Speaker 2: Yeah he's no good. Do you ever think about me in a non-eye doctor way?
Speaker 1: No.
Speaker 2: Ahh.
Speaker 1: But getting over was the hardest thing that I've ever had to do. And I never let myself think about you.
