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: 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 solution: 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.

Problem: Speaker 1: I can't even believe this! I really come off that badly? 
Speaker 2: Oh! It's okay, you calm down after a while and then people can see how really sweet and wonderful you really are. 
Speaker 1: Oh good. Good, because I'm sure this interview is gonna last a couple of weeks. 
Speaker 2: All right, don't freak out! Okay? I-I will help you. How long before you have to leave? 
Speaker 1: An hour. 
Speaker 2: I can't help you. 
Speaker 1: Phoebe! 
Speaker 2: All right, all right, we'll just do our best. Okay? So let's say I'm the interviewer and I'm meeting you for the first time. Okay. "Hi! Come on in, I'm uh, Regina Philange." 
Speaker 1: Chandler Bing. 
Speaker 2: Bing, what an unusual name. 
Speaker 1: Well you should meet my uncle, Bada. I'll let myself out.
