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'.

Speaker 1: Oh! Hey, Mr. Treeger. 
Speaker 2:: Hey. 
Speaker 2:: What are you doing? 
Speaker 1: Ummm. Oh! I'm sorry. It's a little old but... 
Speaker 2:: No! You're clogging up the chute that I spent a half-hour unclogging! 
Speaker 1: I'm sorry. I didn't-I don't come in here a lot. 
Speaker 2:: Oh yeah, of course you don't! 
Speaker 1: No. 
Speaker 2:: 'Cause you're a little princess! "Daddy, buy me a pizza. Daddy, buy me a candy factory. Daddy, make the cast of Cats sing Happy Birthday to me..." 
Speaker 1: I didn't... I never said that. 
Speaker 2:: You think you could make a mess and the big man in coveralls will come in here and clean it up, huh? Well, why don't think of someone else for a change? 
Speaker 1: Okay, I'm sorry.
