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: Oh good, you haven't left yet.
Speaker 2: Where have you been?
Speaker 1: I got held up at Dr. Gettleman's office. There was some guy that freaked everybody out.
Speaker 3: Well, you got here just in time. I really have to go buddy.
Speaker 1: Oh man.
Speaker 2: Promise to call me when you land.
Speaker 3: Of course I will call you. I love you.
Speaker 2: I love you too.
Speaker 4: Okay, wow, wow, wow. Watch the tongue people, we've got a baby over here.
Speaker 5: Bye Chandler.
Speaker 3: Awww. Bye!
Speaker 4: Bye honey.
Speaker 3: What's the matter Joe?
Speaker 6: I'm mad at you for leaving! You're nothing but a big leaver. Big leaver with a stupid suitcase.
Speaker 3: Any chance you are trying to pick a fight to make all this easier?
Speaker 6: Dude, you see right through me!!
Speaker 3: Well, bye Mon, bye Ross, Rachel, bye Emma!
Speaker 5: Okay, bye-bye! Good trip!
Speaker 2: Chandler, wait. It goes: Old job, new job, you. This is just something I have to do.
Speaker 3: I know.
Speaker 2: I love you so much.
Speaker 3: I know that too.
Speaker 3: Don't worry, I'll be back before you know it. Yes it will be the same. Because I know, that's how. I promise.
Speaker 6: Double promise? Call me when you land.
Speaker 2: Can I talk now?
Speaker 6: Okay, bye.
Speaker 2: Joey?
Speaker 6: He had to board.
