Given the task definition, example input & output, solve the new input case.
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: 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?
Output: 1
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 case for you: Speaker 1: Y'know, I don't like to brag about it, but I give the best massages!
Speaker 2: All right, then massage me up right nice!
Speaker 2: Ah! Ahh!! Ahh!!
Speaker 1: It's so good, isn't it?
Speaker 2: It's so good I don't know what I've done to deserve it!
Speaker 1: Say good-bye to sore muscles!
Speaker 2: Good-bye muscles!!
Speaker 2: I'm telling you, she gives the worst massages ever!! Okay, it was like she was torturing me for information. And I wanted to give it up I just-I didn't know what it was!
Speaker 3: Chandler, if it really hurts that bad you should just tell her.
Speaker 2: Look, for the first time in my life I'm in a real relationship. Okay, I'm not gonna screw that up by y'know, telling the truth.
Output:
2
