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'.
One 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?
Solution is here: 1
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.

Now, solve this: Speaker 1: Rachel? 
Speaker 2: Yeah. 
Speaker 1: I'm, uhh, making up flyers trying to get new massage clients. So, can I come to Bloomingdale's and use the copy machine. 
Speaker 2: Well, sure, but they might think it's kinda weird considering I don't work there anymore. 
Speaker 1: Oh my God. What happened? 
Speaker 2: I-I, got a job at Ralph Lauren. 
Speaker 1: Well that's great! Congratulations!! 
Speaker 2: Yeah. A year ago.. 
Speaker 1: You've lasted a whole year. Good for you. 
Speaker 2: But, Pheebs, you can still use the copy machine where I actually work. But, just come by at lunch so my boss doesn't see you. Cause Kim will just freak out and she already doesn't like me very much. 
Speaker 3: That's weird. I don't think my boss likes me either. 
Speaker 4: I don't think mine likes me either. 
Speaker 5: Maybe it's a universal thing? 
Speaker 6: Or maybe, it's because you're hanging around here at 11:30 on a Wednesday. 
Speaker 3: Yeah let's head off to work. 
Speaker 4: We should go.
