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'.

Let me give you an 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?
The answer to this example can be: 1
Here is why: 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.

OK. solve this:
Speaker 1: Wanna make it more interesting? 
Speaker 2: How much were you thinking? 
Speaker 1: Ten bucks a game? 
Speaker 2: Make it fifty! 
Speaker 1: I'll make it a hundred! 
Speaker 2: One thousand... 
Speaker 3: OK! 
Speaker 1: To see who goes first, you got a quarter? 
Speaker 2: No... Either of you girls got a quarter? 
Speaker 3: Honey, try to focus the trash talk on him! 
Speaker 4: Monica, you call it. 
Speaker 2: Heads! No, Tails! He-he-heads! 
Speaker 4: Tails! 
Speaker 2: Ow, what are the chances! 
Speaker 2: Ha! My point! 
Speaker 1: Oh, no! I don't think so! You know, according to standard table tennis rules if at any time a player uses his non racket bearing hand to touch the playing surface he or she forfeits the point. 
Speaker 4: He was a lawyer!
