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: Okay you guys, I got a little more written. Are you ready? 
Speaker 2: Yeah. O-okay. 
Speaker 1: "When I think of the love that these two givers and receivers share, I can not help but envy the lifetime ahead of having and loving and giving and..." And then I can't think of a good word for right here. 
Speaker 3: How about receiving? 
Speaker 1: Yes! 
Speaker 2: See Joe, not that that's not grrreat! But, one of the cool things about having somebody we know perform the ceremony is that it can be about us! Y'know, it can be more personal. You can tell stories about us! 
Speaker 1: Ooh, like the time you and I went to Atlantic City and I made you laugh so hard you threw up your whole steak?! Remember? 
Speaker 2: No, not us... Us! 
Speaker 1: I gotcha. Sorry. So, did you ever make him throw up a whole anything? 
Speaker 4: Did you ever feed him a poison capsule that made him bleed from the eyes? 
Speaker 3: It doesn't say that! 
Speaker 4: Oh! Suddenly somebody knows all about the side affects! 
Speaker 2: See Joe, we want you to tell stories but y'know, romantic stories. Nice stories. 
Speaker 1: Oh. Okay. Ooh! Ooh! Okay, maybe I'll talk about London! Y'know when you two hooked up! Only, only I won't say hooked up. I'll say, "Began their beautiful journey..." 
Speaker 3: There you go!
