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: Hey! 
Speaker 2: Hey, waitwait, aren't you the guy that plays the butt in the new Al Pacino movie? 
Speaker 3: Nope. 
Speaker 4: No? What happened, big guy? 
Speaker 5: "Big guy?" 
Speaker 4: It felt like a 'big guy' moment. 
Speaker 3: I got fired. 
Speaker 1: Oh! 
Speaker 3: Yeah, they said I acted too much with it. I told everybody about this! Now everybody's gonna go to the theatre, expecting to see me, and... 
Speaker 6: Oh, Joey, you know what, no-one is gonna be able to tell. 
Speaker 3: My mom will. 
Speaker 5: Something so sweet and...disturbing about that. 
Speaker 3: Y'know, I've done nothing but crappy plays for six years. And I finally get my shot, and I blow it! 
Speaker 2: Maybe this wasn't your shot. 
Speaker 4: Yeah, I mean... I think when it's your shot, y'know, you-you know it's your shot. Did it... feel like your shot..? 
Speaker 3: Hard to tell, I was naked. 
Speaker 7: No, I don't think this was your shot. I mean, I don't even think you just get one shot. I really believe big things are gonna happen for you, I do! You've gotta just keep thinking about the day that some kid is gonna run up to his friends and go 'I got the part! I got the part! I'm gonna be Joey Tribbiani's ass!'. 
Speaker 3: Yeah? That's so nice!
