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: I've missed you so much! No, I'm not gonna ask you to get back together because I know we want different things, but just to be with you one more night. 
Speaker 2: I know, I want that too, but is that going to make it too hard? 
Speaker 1: It can't be any harder than this... I mean, If I had known the last time I saw you would be the last time, I... I would have stopped to memorize your face, the way you move, everything about you. If I had known the last time I kissed you would have been the last time... I never would have stopped. 
Speaker 3: Kiss him, you fool!! 
Speaker 2: What? 
Speaker 3: Didn't you hear that speech? If you don't kiss him then I will! 
Speaker 2: Oh, I missed you so much! 
Speaker 4: I knew you'd be here! 
Speaker 1: Oh, crap! 
Speaker 2: Who is this? 
Speaker 1: My friend Manny. I asked him to keep me away from you. 
Speaker 3: Hi, that's what I'm doing for Phoebe! 
Speaker 5: Well, you are not doing a very good job! 
Speaker 3: Excuse me? 
Speaker 5: What's with the kissing? 
Speaker 3: Hey, at least I knew where my guy was. 
Speaker 5: Oh yeah yeah, thank God you were here to oversee all the kissing! 
Speaker 3: You didn't hear the speech! 
Speaker 5: I've heard the speech: "if he knew it was gonna be the last time he saw her... " 
Speaker 3: Hey, it was very moving! You're just heartless! 
Speaker 5: You're weak! 
Speaker 3: You're... weird! 
Speaker 5: Your pants are undone! 
Speaker 3: Oh! 
Speaker 5: Where did they go? 
Speaker 3: Damn it! 
Speaker 5: Oh we blew it. I blame myself. 
Speaker 3: And I blame you too.
