You will be given a definition of a task first, then some input 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: Hey, so? Are you gonna do it?
