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: Hi, this Phoebe from Empire Office Supplies, can I speak to your supply manager please? Earl, thanks. Hi Earl, this is Phoebe from Empire Office Supplies I'd like to talk to you about your toner needs.
Speaker 2: I don't need any toner.
Speaker 1: I'm hearing what you're saying, but at our prices everyone needs toner.
Speaker 2: Not me.
Speaker 1: May I ask why?
Speaker 2: You wanna know why. You wanna know why?
Speaker 1: I surely do!
Speaker 2: Okay, I don't need any toner because I'm going to kill myself.
Speaker 1: Umm, is-is that because you're out of toner?
Answer:
