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?
Example solution: 1
Example explanation: 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.

Problem: Speaker 1: Are we in London?
Speaker 2: What are you doing here? You can't be here!
Speaker 3: I've uh, I've come to talk to Ross.
Speaker 3: What?
Speaker 4: Nothing. No, nothing.
Speaker 3: I was going to call him, but...
Speaker 2: Oh, you came to tell him you love him! I knew it! I was right! I'm right, right?
Speaker 3: I'd really rather talk to him.
Speaker 2: Oh.
Speaker 3: I uh, I've been to his apartment and he wasn't there, and uh. I need to talk to him, so do you have any idea where he is?
Speaker 3: Ross, are you there? Ross, I don't know if you can hear this but... I'm gonna talk anyway, uh, I'm in the States with you sister and your friends and it's all over with Colin. I came here to tell you that, and to tell you-Yes, Joey you can have all the chocolate you want, just take it! Uh, I came here to tell you that I love you.
Speaker 5: I love you too! I'm, I'm gonna call you right now from the phone booth! You can't hear me.
Speaker 3: I wish I could know if you'd heard any of that. I suppose I've either just told you I love you or given my neighbours a good laugh. Mrs. Newman if you're listening, bugger off this in none of your business. I suppose there's not much chance you did heard that, and there's the call waiting so, I should go. Oh well. Hello.
Speaker 5: Hi.
Speaker 3: Ross, I love you!
Speaker 5: Ohh! Thank you.
