Teacher: 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'.
Teacher: Now, understand the problem? If you are still confused, see the following 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?
Solution: 1
Reason: 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.

Now, solve this instance: Speaker 1: Hey, what's-what's going on?! 
Speaker 2: Well, I think, I think Ross knows about me and Monica. 
Speaker 3: Dude! He's right there! 
Speaker 4: I thought you were my best friend, this is my sister! My best friend and my sister! I-I cannot believe this! 
Speaker 2: Look, we're not just messing around! I love her. Okay, I'm in love with her. 
Speaker 5: I'm so sorry that you had to find out this way. I'm sorry, but it's true, I love him too. 
Speaker 4: My best friend and my sister! I cannot believe this. You guys probably wanna get some hugs in too, huh? Big news! 
Speaker 1: Awww, no, it's okay, we've actually known for a while. 
Speaker 4: What? What? What?! You guys knew? You all knew and you didn't tell me?!! 
Speaker 1: Well, Ross, we were worried about you. We didn't know how you were going to react. 
Speaker 4: You were worried about me? You didn't know how I was going to react? 
Speaker 3: Okay, all right, whew! What do you say we all clear out of here and let these two lovebirds get back down to business? Hey-hey-hey, I-I-I'm just talking here, he-he's the one doing your sister.
