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: How was the pediatrician?
Speaker 3: Oh, I really liked him. Yeah, it was really, really, really good.
Speaker 1: You promised you wouldn't say anything.
Speaker 3: I know. Ross still sees his pediatrician!!! I don't care!
Speaker 2: Are you serious? You still see Dr. Gettleman?
Speaker 1: He's a brilliant diagnostician!
Speaker 4: Diagnostician or boo-boo fixer?
Speaker 3: Ross, seriously! You've gotta go to an appropriate doctor.
Speaker 1: Why? Why? I know it's a little weird, but hey, he's a great doctor, okay? He knows my medical history, and every time I go in there, he makes a big deal. 'Ah look, it's my favorite patient!'
Speaker 4: Does he say that before he sticks his thermometer in your touchy?
Speaker 1: Hey, I seem to remember someone bringing his security blanket to college!
Speaker 4: That was not a security blanket! That was a wall-hanging!
Speaker 1: It didn't spend much time on the wall!!!
