You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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: 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?
Solution: 1
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.

New input: Speaker 1: May I help you? 
Speaker 2: Yes. We're here to make a rather sizeable donation to the children. 
Speaker 1: Well, any contribution, large or small, is always appreciated. 
Speaker 2: Well, I think you're gonna appreciate it the crap out of this one. 
Speaker 1: Well, this is very generous! 
Speaker 2: And we don't want any recognition. This is completely anonymous. 
Speaker 3: Completely anonymous. From two kind strangers. 
Speaker 2: Mr. X and Phoebe Buffay. 
Speaker 1: Well if you like, we can include your names in our newsletter. 
Speaker 3: Not necessary. 
Speaker 2: Buffay is spelled B-U-F-F-A-Y. 
Speaker 3: And "X" is spelled uhm... "Mike Hannigan". 
Speaker 1: Right. Well, on behalf of the children: thank you both very much. 
Speaker 2: Sure, I so glad we did this. It feels so good! 
Speaker 3: It does. It feels really good! 
Speaker 2: Oh, look! And we get these free t-shirts! 
Speaker 1: Oh, actually, that's the shirt I wore to the gym. 
Speaker 2: Mhm... it's moist.
