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: Monica, your Sweet Sixteen was like a million years ago.
Speaker 2: And yet, here we are doing it again.
Speaker 1: Ugh, Monica I don't want to steal your stupid thunder!
Speaker 2: Oh please! Why else would you have made out with Ross?!
Speaker 3: Got me.
Speaker 1: All right, easy mimey, the moment has passed, it ain't gonna happen!
Speaker 2: I just thought it would be nice if I could have just this one night!
Speaker 1: I swear, I never wanted any part of your night!
Speaker 2: Oh, is that why you did it the secret hallway where nobody ever goes?!
Speaker 3: Uh, Rachel, I've been thinking. I don't think us getting together tonight is such a good idea. I'm calling it off.
Speaker 4: Why to save your dignity my man.
Speaker 1: Monica, why? Why would I ever want to take away from your night?
Speaker 2: I don't know! I don't-maybe you're feeling a little resentful. Maybe ah, maybe you thought you'd get married first! Maybe you can't stand the fact that your formally fat friend is getting married before you!
Speaker 1: Oh wow. That-y'know what? That is so unfair. Y'know what? Now I want to steal your thunder!
Example Output: 1
