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: Okay look, Ross, just so you know that since Lizzie likes you so much, I've decided to accept the fact that you're going out with her. 
Speaker 2: Really? That okay, that's great. 
Speaker 1: Yeah. But then I changed my mind. I'm funny like that. So I told Lizzie, now I'm telling you, I don't want you seeing my daughter anymore. 
Speaker 2: All right look, I-I realize it upsets you. 
Speaker 1: Yes it does. 
Speaker 2: But, Elizabeth and I are-are both adults and so I don't think there's really anything you can do about it. 
Speaker 1: I'll call the university and tell them about your relationship and have you fired. 
Speaker 2: Ohh! A man with a plan!
