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: Well uh...I think I want to take Chandler. 
Speaker 2: Phoebe-Phoebe-Phoebe-Phoebe-Burrrrr! 
Speaker 3: You really want to take me? 
Speaker 1: Yeah! Yeah! I mean I'm sorry, I wish I can take everybody, but y'know Chandler always supported my career. He's paid for acting classes and head shots and stuff and well this will be my way of paying you back. 
Speaker 3: So you're never actually going to pay me back? 
Speaker 4: Wait a minute, just because he paid for your head shots you're gonna take him? Joey, I don't think you're comprehending just how slutty this dress is! 
Speaker 1: It's not just the stuff he paid for, I mean it's-it's everything. Y'know? He read lines with me. He-he went with me on auditions when I was really nervous, and then he consoled me after I didn't get parts that I really wanted. You always believed in me man. Even, even when I didn't believe in myself. 
Speaker 3: I always knew you were gonna make it. I'm so proud of you. 
Speaker 1: Thanks. That means a lot to me. 
Speaker 2: Mon, maybe one of these guys wants to wear your dress.
