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 is below.
Q: 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?
A: 1
Rationale: 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: Surprise. 
Speaker 2: Oh my gosh, wow. Monica. Oh my god. Mom. This is so great. 
Speaker 3: Happy birthday sweetie. 
Speaker 2: Wow you, you. I had no idea. 
Speaker 4: Really? 
Speaker 2: No, I knew. 
Speaker 4: All right. 
Speaker 5: Ok, everybody, there's food and drinks on the table. Go across the hall. 
Speaker 4: What? 
Speaker 2: What? 
Speaker 5: Right now, Joey and Chandler's, go now. 
Speaker 2: Why. 
Speaker 5: Just go. 
Speaker 1: Surprise. 
Speaker 6: Happy birthday sweetpea.
